Breast cancer may cause abnormal cell growth
in one/both breasts. The cells can invade tissue
nearby, form a tumor, spread to lymph nodes or
other parts of your body. Risk factors you cannot
change: your age and genes. Risk factors you
can change: your weight, activity and hormone
therapy after menopause.
Breast cancer can cause a painless lump or
thickening in the breast/underarm to grow. It may
also cause the skin to dimple, like an orange peel.
Nipple changes; it may turn inward or look scaley.
