Approximately 5 to 20 percent of breast cancer cases are hereditary, according to the oncologist. Here’s what you need to know.
Breast cancer is one of the most common cancers, especially prevalent in India. Key contributing factors include lifestyle, environment, and genetics. But can breast cancer be hereditary? In an interview with HT Lifestyle, Dr. Abhaya Kumar S.M., Consultant in Medical Oncology at Manipal Hospital Whitefield, explained, “Approximately 5 to 20 percent of breast cancer cases are hereditary, often running in families for generations. However, it’s important to remember that not all breast cancers are inherited.”
Causes of Breast Cancer
“Key lifestyle factors contributing to breast cancer include urbanization, high-fat, low-vegetable diets, physical inactivity, and obesity,” noted Dr. Abhaya Kumar S.M. “Late marriages, delayed childbirth, and avoiding breastfeeding are also significant but often overlooked risk factors for developing breast cancer.”
Symptoms to Watch For
“Breast cancer patients often notice a painless, hard lump fixed in the breast tissue,” explained Dr. Abhaya Kumar S.M. “As the disease advances, symptoms may include skin thickening, ulceration, discoloration, nipple retraction, and discharge—especially bloody discharge. In more advanced stages, a lump may also appear in the armpit.”
Can Breast Cancer Be Detected Early?
Early detection is crucial for effective cancer treatment. “Breast cancer can be identified at an early stage through mammography, which is essentially an X-ray of the breast tissue,” explained the oncologist. “Screening mammograms are invaluable for spotting breast cancer early, which greatly improves treatment outcomes and increases the likelihood of a cure. Therefore, regular annual mammograms are recommended for all women starting at age 40.”
