Every year in October, we observe breast cancer awareness month to spread awareness and educate people about this cancer, most common in women. As per the World Health Organisation (WHO) is the most common cancer in women in 157 countries out of 185, in 2022. In India, it accounts for 27% of all cancers. What Is Breast Cancer?It is a cancer that begins as a growth of cells in the breast tissue. As per WHO, it begins inside the milk ducts of the breast, and the earliest form is not life-threatening and can be detected in the early stages. Cancer cells spread into nearby breast tissue, creating tumours that cause lumps or thickening. Invasive cancers can also spread to nearby lymph nodes or other organs. While the exact source of what causes it has not been yet found, many claims are already existing around it. To check whether these claims are valid, we spoke to Dr Namrata Singal Sawant, Director and Senior Breast & Women's Imaging Consultant Radiologist at Vcare Imaging Diagnostic Centre, Mumbai. ClaimsWearing A Bra Causes Breast CancerThis idea was fueled by the 1995 book called Dressed to Kill by Sydney Ross Singer and Some Grismaijer which claimed that women who wear underwire bras for 12 hours a day have a much higher risk of developing breast cancer. The book claims that it restricts the lymph system, which can result in a build-up of toxins in the breasts. However, there is no credible research that shows a link between the two.Dr Namrata says, "While many of my patients ask me this question, especially about underwired bras or black bras; there has been no scientific evidence to claim the same. Although ill-fitting bras do cause chest pain or breast pain sometimes if too tight. But not cancer."Sugar Consumption Can Caused Increased Risk of Breast Cancer"It might be associated with many other health issues but has not been associated with breast cancer yet. However, keeping the sugar levels under control is very important for health healing of any breast infections or inflammatory disorders. Diabetic mastopathy is an important mimicker of breast cancer on imaging," says the doctor. Wearing Black-dyed Clothes Can Cause Breast CancerThe doctor says that it has not been proven by any scientific studies; however, wearing clothes with natural fibres and maintaining personal hygiene in the form of cleaning ourselves and our clothes regularly is a must. Pregnancy Increases The Risk of Breast CancerAs per the National Cancer Institute, the older a woman is when she has her first full-term pregnancy, the higher her risk of breast cancer. "Having our conventional reproductive customs like a first child before the age of 30 years and breastfeeding has been known to be associated with lower risks," says Dr Namrata. She also highlights the reports of Hormonal replacement therapy associated with increased risk of breast cancer. Therefore, pregnancy does not increase the risk of breast cancer. Men Cannot Have Breast CancerWhile it is rare, male breast cancers can happen. As per WHO, approximately 99% of breast cancers occur in women and .5 to 1% occur in men. "In fact, any lump, nipple discharge or skin changes must be looked up with higher suspicion in males as compared to females. In fact, males do not have fibroadenomas which are the most common benign lumps in females. There are no screening programmes for breast cancer for males as of now. Hence, it is very important to bring this awareness amongst men and also in our family to be aware of its symptoms," explains Dr Namrata. Breast Cancer Cannot Happen Again"Well! Some types of breast cancer when diagnosed early have excellent prognosis to treatment. Whereas there are others especially “Triple-negative types” which are notorious for poor prognosis and recurrence. If the cancer is diagnosed late, or positive margins have been left behind during breast conservative treatment or some kind of treatment failure, there are definite chances of recurrence," explained the doctor.
