Diet and Breast Cancer: Navigating your relationship with food during cancer treatment

If you have breast cancer, what should you eat? Is there any food to avoid? Is there something you could do when food becomes unappetising? Patients may experience a changing relationship with food. Here are four tips that may help. 1. Manage Eating Problems While cancer treatments sometimes make it challenging to eat or drink, you need additional calories and protein for wound healing and recovery after treatments like breast surgery [1].To manage eating difficulties such as appetite loss, nausea, and changes in their sense of taste or smell that make tasty food unpleasant [2] [3], try the following [2] : Eating smaller amounts more often instead of large meals Eating foods that are easy on the stomach e.g. bananas and rice Keeping easy-to-carry snacks for when you feel like eating, e.g. granola bars Changing the form of foods e.g. turn sliced fruit into smoothies Sipping only small amounts of liquids during meals, as eating and drinking simultaneously may make you feel bloated Choose foods that appeal to you and do not force yourself to eat food that makes you feel ill Eating well can help you regain strength and improve how you feel after completing treatment. Here’s how you can do that [2]  [4]. : Freeze portions of soups, curry, stews and other dishes for times when you do not have the time or energy to cook Prepare simple, easy-to-make meals that you enjoy. Ideally cook more than you need so that you cook once and eat twice Eat a wide variety of fruits and vegetables that provide vitamins, minerals and fibre 2. Consult your doctor before making drastic dietary changes Advice from well-meaning friends and family on what to eat can be overwhelming. While it may be tempting to follow them, it is important to consult your doctor first. You may be considering fasting or wish to avoid eating certain foods that you have been told may worsen the cancer. These fears are rarely true and limiting your food intake has the potential to slow down recovery from cancer treatment and leave you feeling tired and weak [5] If you wish to take vitamin or mineral supplements, check with your doctor or dietitian before doing so, as they may affect how your body copes with treatment [5] [6]. Unproven advice to follow special diets to cure or control your disease, such as cutting out a food group or taking high-dose supplements need to be considered with caution [5]. Following unproven diets may do more harm than good. 3. Be Kind to Yourself You may sometimes feel overwhelmed by friends and family around you who want you to eat more or bring you homecooked favourite meals [7]. Help them to help you by asking them to cook meals you have the appetite to eat. It is times like this when practising self-compassion is essential. You may have both good and bad days when it comes to what you can stomach [2]. Do not feel pressured to eat food from others, as forcing yourself to eat may make you feel worse. Share how you feel with your loved ones. You may worry about upsetting them but having them listen to you may help alleviate the anxiety and distress you have about eating [7] . 4. Make Eating Enjoyable Again For many, eating is a social activity and should be enjoyable [7].Having eating problems and anxiety surrounding what foods you can eat can sour your relationship with food. Try making mealtimes as pleasant and relaxing for you as possible. Cook and eat together with loved ones, try new recipes, play music or even brighten up your dining table with flowers [2] [8]. Eating your favourite foods when you feel well will allow you to enjoy eating and avoid associating these foods with feeling sick [2]. . It can be hard to think positively about eating whilst battling cancer, but food should be seen as necessary fuel to nourish and energise the body instead of being a source of stress and worry. The breast cancer journey is difficult, and worrying about what to eat and how to eat makes things even more burdensome. Give yourself grace during this period and consult your doctor about dietary concerns.

Breastfeeding, Breast Cancer, and Being Breast Aware

Most mothers would agree that breastfeeding is one of the most gratifying yet challenging and sacrificial parts of being a mum. On top of battling latch issues, juggling the delicate balance between oversupply and undersupply, and being chained to a breast pump several times a day, mothers often grapple with breastfeeding complications such as sore/damaged nipples, engorgement, clogged ducts and mastitis. Such complications present as nipple changes and/or discharge and breast lumps; which are identical to symptoms of breast cancer. How can you tell the difference? Let’s tackle the myths associated with breastfeeding and breast cancer. Does developing a lump during breastfeeding mean breast cancer? Developing breast lumps during lactation is very common and is often non-cancerous. Lumps typically develop due to clogged ducts or mastitis. Clogged ducts occur from blocked milk ducts, which if not cleared, can lead to mastitis (breast inflammation). Mastitis can also be caused by infection. Occasionally, mastitis can be complicated by breast abscess formation (pus collection). Benign lumps such as cysts (fluid sacs) and solid nodules which are not related to breastfeeding can also form during this time. Rarely, a breast lump which is discovered during breastfeeding is due to breast cancer. Can breastfeeding women develop breast cancer?  Breast cancer remains the leading cause of cancer among women in Singapore and one in every 13 women will develop breast cancer in their lifetime.  One in 6 women diagnosed with breast cancer are below 40 years of age.  Cancer may occur in a lady who is breastfeeding though the incidence is low.  While breastfeeding has been suggested to lower a woman’s risk of developing breast cancer, performing self-examination regularly after latching or pumping may allow you to recognise any early changes in your breasts. Can breastfeeding reduce cancer risk?  Yes, it does! Studies have indicated that for every 12 months of breastfeeding, the relative risk of developing cancer is lowered by 4.3%.  This is in addition to the 7.0% reduction in risk observed for every birth [1].  The proposed rationale is the hormonal changes that occur during pregnancy and breastfeeding.  With breastfeeding delaying the return of our menstrual cycle, our bodies are less exposed to oestrogen.  Oestrogen is an important hormone that is produced by our ovaries that assist in puberty, menstrual cycle, reproduction and bone strength.  They are present in our male counterparts in smaller amounts.  Prolonged excessive exposure has been linked to a possible higher risk of breast cancer development [2]. Mammograms are safe for breastfeeding mothers. Can breastfeeding mothers undergo mammograms? Yes, they can! Breast density increases during lactation due to the presence of milk within the breasts, which can obscure findings in mammograms. Lactating mothers are thus encouraged to empty their breasts via direct nursing or pumping prior to their mammograms to improve image clarity and diagnostic accuracy. Breastfeeding mothers of screening age (40 and above) are advised to continue mammographic screening at regular intervals. Lactating mothers experiencing symptoms which need further investigation may undergo mammograms and/or ultrasound studies based on your doctor’s evaluation. Consult with your doctor to determine the most appropriate option for you [3].  Conclusion It is normal for your breasts to change in shape and size after pregnancy and childbirth, whether you breastfeed or not. It is crucial for you to understand and pay attention to your body, as a cancer diagnosis and treatment can affect your life as a mother.
