Since all cancers manifest differently in different people, it’s the same with breast cancer too. So, you might not know you have breast cancer because there may not be any noticeable symptoms. The most common signs and symptoms of breast cancer are:
A lump or lumps in the breast or underarm area
Breast pain
Swelling of the entire breast or part of it
Skin irritation or dimpling of the breast
Nipple pain or inverted nipple (turning inwards)
Nipple discharge (not breast milk)
Thickening of the nipple or breast skin
Redness and scaliness of the nipple or breast skin
