Breast Cancer In New Mothers- Signs To Look For While Breastfeeding

Women are known to be multitaskers, they juggle a number of roles every day at home and work. In the life span of a woman, her body goes through a number of changes during puberty, motherhood and menopause. All of these changes result in hormonal alterations and physical transformations, which might lead to overlooking certain health related concerns. In this article, Dr. Nanda Rajaneesh, Laparoscopic Surgeon at Apollo Spectra Hospital, Bangalore has explained all about breast cancer in new mothers.

Breast Cancer Signs While Breastfeeding

Childbirth is an exhausting process and it is usually followed by an array of sleepless nights, adjustment to a new routine with an infant and a sudden drop in hormone levels as the lactation begins. Breastfeeding is a very emotional phase of motherhood that helps in establishing a bond  between the mother and child. As per a study conducted by Breast Cancer Statistics, one Indian woman is diagnosed with breast cancer every four minutes. It becomes extremely difficult to diagnose breast cancer with new mothers as the symptoms are very similar to that of nursing. Breast Cancer is one of the most prevalent cancers in the world and breastfeeding can mimic certain signs that are also early symptoms of breast cancer. 

New mothers often experience constant fatigue, loss of appetite, and other hormonal changes. While these symptoms are not an immediate cause for alarm, if any of them persist or interfere in day to day activities the person should seek medical help.  

Breast lumps are among the most alarming signs of a larger problem and should be treated immediately. New mothers often tend to ignore these lumps as they assume them to be blocked milk ducts and also due to the lack of awareness regarding primary health conditions.
