When the Dietitian Became the Patient: My Cancer Journey
Almost Five Years Beyond Diagnosis — Nutrition, Lifestyle Changes, Challenges, Lessons and Hope
For years, I was the person sitting across the table from patients, talking about nutrition, lifestyle, disease prevention and recovery.
I was the dietitian.
I encouraged people to listen to their bodies, eat mindfully, stay physically active and take their health seriously.
And then, almost five years ago, I became the patient.
Suddenly, cancer was no longer something I was discussing professionally. It had become a part of my own life.
That experience changed me—not only as a person, but also as a dietitian.
Today, I want to share a part of my journey because I believe that awareness, early medical evaluation, appropriate treatment, nutrition and emotional support all have an important place in the journey through cancer and beyond.
Breast Cancer: More Than Just a Statistic
Breast cancer is one of the most common cancers affecting women. Advances in awareness, screening, diagnosis and treatment have improved outcomes for many women, but the disease continues to affect millions of families.
For me, statistics are no longer just numbers on a page.
They represent women I have met, patients I have counselled, families I have seen struggle—and now, they also represent a chapter of my own life.
My diagnosis taught me something very important:
Even a person who considers herself health-conscious can develop cancer.
I did not drink alcohol.
I did not smoke.
I was physically active and had always believed in staying active.
I had a professional understanding of nutrition and lifestyle.
Yet, cancer happened to me.
This is not meant to create fear or make anyone feel that healthy living is pointless. Quite the opposite.
Healthy habits matter. They can support overall health and may reduce the risk of several diseases, including some cancers. But they cannot provide a guarantee that cancer will never occur.
Cancer is complex, and there is rarely one single reason why an individual develops it.
My Symptoms: I Had to Listen to My Body
Breast cancer does not always present with an obvious lump.
Possible warning signs can include:
- A lump or thickening in the breast or underarm
- A change in breast size or shape
- Changes in the skin of the breast
- Nipple changes
- Nipple discharge
- Persistent swelling
- Changes in the appearance of the breast
- Persistent breast discomfort or pain
In my own case, my presentation was not something I would have simply dismissed as a typical breast lump.
I experienced itchiness in my breast, significant edema, weight gain of around 10 kg, breathlessness and chronic fatigue.
Looking back, one of the biggest lessons from my experience is this:
Know your own body.
You do not have to diagnose yourself.
But if something changes and it doesn't feel right, don't ignore it.
Seek medical advice.
Inflammatory Breast Cancer: A Less Familiar Presentation
There is a relatively uncommon and aggressive form of breast cancer called inflammatory breast cancer (IBC).
Unlike many breast cancers, it may not present as a clearly defined lump.
Possible signs can include:
- Redness or discoloration of the breast
- Swelling
- Skin thickening
- A peau d'orange or "orange-peel" appearance
- Warmth or tenderness
- Changes that may initially resemble an infection or rash
Because inflammatory breast cancer can look different from the more familiar presentation of breast cancer, persistent or unusual breast changes should be medically evaluated rather than self-treated or ignored.
How Was My Cancer Diagnosed?
My diagnostic journey involved several investigations.
In my case, these included:
Ultrasound → MRI → FNAC → PET-CT → Core Biopsy
Each investigation answered different questions and helped my medical team understand what was happening.
A biopsy is particularly important because imaging alone cannot definitively establish whether a suspicious lesion is cancer.
The biopsy allows the tissue to be examined and helps determine the type and characteristics of the cancer, which in turn helps doctors plan appropriate treatment.
Understanding Breast Cancer Subtypes
Breast cancer is not one single disease.
It can have different biological characteristics, and treatment is therefore individualized.
Hormone Receptor-Positive Breast Cancer
Some breast cancers have receptors for hormones such as estrogen and/or progesterone.
These are commonly described as:
- ER-positive — estrogen receptor positive
- PR-positive — progesterone receptor positive
Hormone therapy may be recommended for people whose cancers are hormone receptor positive.
HER2-Positive Breast Cancer
Some breast cancers have increased levels of a protein called HER2.
HER2-positive breast cancer has specific targeted treatment options, and determining HER2 status is therefore an important part of cancer evaluation.
The development of HER2-targeted therapies has significantly expanded treatment options for people with HER2-positive breast cancer.
Triple-Negative Breast Cancer
Triple-negative breast cancer does not have estrogen receptors, progesterone receptors or excess HER2.
Because hormone therapies and HER2-targeted therapies do not work against these particular targets, treatment approaches are different and may include chemotherapy, surgery, radiation and, in selected situations, immunotherapy or other treatments.
Understanding the Stage
Once breast cancer is diagnosed, doctors determine its stage.
Staging helps establish how extensive the disease is and whether it has spread to nearby lymph nodes or other parts of the body.
Breast cancer staging and treatment decisions are complex. The stage, tumour biology, receptor status, overall health and several other factors can influence treatment.
This is why two people with "breast cancer" may receive completely different treatment plans.
Treatment: There Is No One-Size-Fits-All Approach
Depending on the type and stage of breast cancer, treatment may involve one or more of the following:
Surgery
Surgery may involve removing the tumour while preserving the breast, when appropriate, or removing the breast through mastectomy.
Chemotherapy
Chemotherapy uses medicines to destroy or control cancer cells. It may be given before or after surgery depending on the individual situation.
Possible side effects include fatigue, nausea, changes in appetite, hair loss and increased susceptibility to infections.
Radiation Therapy
Radiation uses high-energy radiation to destroy cancer cells in a specific area. It is often used after surgery in selected patients.
Hormone Therapy
Hormone therapy may be used when breast cancer is hormone receptor positive.
Targeted Therapy
Targeted treatments act on specific characteristics of cancer cells. HER2-targeted therapies are an important example.
Immunotherapy
For selected breast cancers, immunotherapy may be part of treatment.
The important message is that treatment should always be individualized by the oncology team.
The Dietitian Became the Patient
This was perhaps the most difficult transformation for me.
As a dietitian, I was accustomed to giving advice.
Suddenly, I had to receive it.
I had to undergo investigations.
I had to wait for reports.
I had to listen to medical terminology that I had previously encountered professionally but now had a deeply personal meaning.
I experienced the uncertainty that patients and families feel.
And I learned that knowing the science does not make the emotional journey easy.
There were days when I was strong.
There were days when I was frightened.
There were days when I simply wanted life to feel normal again.
Nutrition During Cancer Treatment
One of the biggest misconceptions I encountered was the idea that there is one special "cancer diet."
There isn't.
Nutrition during cancer treatment should be individualized according to:
- The type of cancer
- Treatment being received
- Appetite and food tolerance
- Nutritional status
- Weight changes
- Blood investigations
- Gastrointestinal symptoms
- Other medical conditions
- Treatment-related side effects
During treatment, the priorities may include maintaining adequate energy, protein, fluids and essential nutrients, while adapting food choices to symptoms and treatment tolerance.
For example, someone experiencing nausea may need a very different meal pattern from someone dealing with mouth sores, diarrhoea, constipation or difficulty swallowing.
Food Safety During Chemotherapy
When chemotherapy or other treatments weaken the immune system, food safety becomes especially important.
Some practical precautions include:
- Avoiding raw or undercooked meat, eggs and seafood
- Choosing pasteurized milk and dairy products
- Washing fruits and vegetables thoroughly
- Avoiding foods with questionable hygiene or storage
- Refrigerating leftovers promptly
- Avoiding cross-contamination between raw and cooked foods
- Taking extra care with ready-to-eat foods
Food safety recommendations should always be individualized according to the patient's treatment and blood counts.
What About Soy?
Soy has often been surrounded by confusion, particularly among women with hormone-sensitive breast cancer.
Foods such as tofu, soybeans, edamame and unsweetened soy milk contain naturally occurring compounds called isoflavones.
Current evidence does not support the idea that normal dietary amounts of soy foods should automatically be avoided by women with breast cancer.
However, concentrated soy or phytoestrogen supplements are different from ordinary foods and should not be taken without discussing them with the treating medical team.
Does Sugar "Feed" Cancer?
This is one of the most common questions I hear.
The simple statement that "sugar feeds cancer" is an oversimplification.
All cells in our body use glucose as an energy source. Removing all dietary sugar does not selectively starve cancer cells.
At the same time, this does not mean that unlimited sweets and sugary drinks are beneficial.
A balanced diet, appropriate calorie intake, adequate protein, fibre-rich foods and a healthy body weight remain important components of overall health.
The goal is not fear of one food.
The goal is overall dietary quality.
My Lifestyle Before Cancer
There is something I particularly want to emphasize from my own experience.
I did not smoke.
I did not drink alcohol.
And I was physically active.
I had always believed in movement and maintaining an active lifestyle.
I mention this because sometimes people assume that cancer happens only to those who have an "unhealthy lifestyle."
That is not true.
Healthy lifestyle practices are important, but they cannot eliminate cancer risk completely.
There are many factors involved—including age, genetics, family history, reproductive factors, environmental exposures and chance.
Therefore:
Please don't blame yourself.
A cancer diagnosis is not proof that you "did something wrong."
Breastfeeding, Exercise and Healthy Weight
Some lifestyle factors are associated with breast cancer risk.
Breastfeeding is associated with a modest reduction in breast cancer risk, and physical activity is also associated with lower risk.
Maintaining a healthy body weight, particularly after menopause, may also be beneficial.
I had breastfed my child and remained physically active.
Again, my experience reinforces an important point:
Risk reduction is not the same as risk elimination.
Healthy habits are worth maintaining because they support our overall health—not because they offer a guarantee against cancer.
Life After Cancer
Cancer does not end when treatment ends.
For many survivors, life after treatment brings a different set of challenges.
There may be:
- Fatigue
- Changes in body image
- Fear of recurrence
- Changes in appetite or weight
- Hormonal changes
- Sleep difficulties
- Emotional ups and downs
- Changes in work and family life
- The need to rebuild physical strength
Support from family, friends and healthcare professionals can make a tremendous difference.
And sometimes, simply having someone who understands what you have been through can be healing.
Physical Activity: Something I Continue to Believe In
Physical activity has always been an important part of my life.
Even during difficult periods, movement helped me feel connected to my body.
For cancer survivors, physical activity can support physical functioning, cardiovascular health, strength, mood and overall quality of life.
The amount and intensity should be appropriate for the individual's medical condition and recovery stage.
You don't have to become an athlete.
A walk.
Some stretching.
Strength exercises.
Household activity.
Gradually increasing movement.
Every bit can matter.
A Dietitian's Approach to Nutrition After Cancer
As a dietitian, I don't believe in extreme diets, miracle foods or "detox" programmes.
Instead, I encourage a balanced eating pattern built around:
🥦 Plenty of vegetables and fruits
Aim for variety and include different colours.
🌾 Whole grains
Choose foods such as oats, whole wheat, millets, brown rice and other minimally processed grains according to your preferences and tolerance.
🫘 Pulses and legumes
Dal, beans, chickpeas, peas and other legumes provide protein and fibre.
🥛 Adequate protein
Protein needs depend on the individual and may come from pulses, dairy, eggs, fish, chicken or other suitable sources.
🥜 Healthy fats
Nuts, seeds and appropriate amounts of healthy oils can form part of a balanced diet.
💧 Adequate hydration
Fluid requirements vary from person to person and may change during treatment.
The focus should be on adequacy, balance, variety and sustainability.
What About Supplements?
This is an area where cancer patients need to be particularly careful.
"Natural" does not automatically mean "safe."
Some herbal products and high-dose supplements can interact with medicines or may not be appropriate during cancer treatment.
Please do not start supplements, herbal preparations or "anti-cancer" products simply because someone recommends them online.
Always discuss supplements with your oncologist or qualified healthcare professional first.
The Lessons My Cancer Journey Taught Me
Almost five years after my diagnosis, I can say that cancer changed me.
But it did not take away my identity.
I am still a dietitian.
I am still passionate about nutrition.
I am still physically active.
I still believe in eating well and living well.
But now I understand my patients' journeys in a way that I could never have understood before.
I know what it feels like to wait for a report.
I know what uncertainty feels like.
I know how much a kind word can mean.
I know that sometimes a patient doesn't need another lecture about food.
Sometimes they simply need someone to say:
"I understand. You are not alone."
From Dietitian to Patient—and Back Again
My cancer journey has given me a different perspective on nutrition.
Food is important.
Lifestyle is important.
Physical activity is important.
But so are early evaluation, appropriate medical treatment, emotional support, sleep, relationships and quality of life.
There is no single food that prevents cancer.
There is no single food that cures cancer.
And there is no perfect lifestyle that can guarantee that cancer will never happen.
What we can do is take care of the things that are within our control.
Eat nourishing food.
Stay active.
Avoid tobacco.
Avoid or limit alcohol.
Maintain a healthy weight where possible.
Attend appropriate screening and medical appointments.
Listen to changes in your body.
And seek professional medical advice when something doesn't feel right.
My Message to Every Woman Reading This
Please don't wait until something becomes severe before seeking help.
Know your breasts.
Know what is normal for you.
Pay attention to changes.
Don't be embarrassed to discuss unusual symptoms.
And don't allow fear to stop you from getting checked.
Early detection does not guarantee a particular outcome, but timely evaluation can make an important difference in diagnosis and treatment planning.
Almost Five Years Later…
I began this journey as a dietitian who became a patient.
Today, I look at that experience differently.
Cancer became one of the hardest chapters of my life—but it also became one of my greatest teachers.
It taught me resilience.
It taught me gratitude.
It taught me to listen.
And most importantly, it taught me that being a healthcare professional does not make us immune to illness.
We are human first.
Today, I continue my work as a dietitian with an even deeper understanding of the people who sit across from me.
I don't just counsel patients anymore.
I understand what it means to be one.
And if sharing my story encourages even one woman to pay attention to her body, seek timely medical advice, take care of her nutrition, or feel a little less alone after a diagnosis, then sharing it has a purpose.
Cancer was a chapter of my life.
It is not the whole story.
