The probability of breast cancer being inherited is around 10%. First of all, it is important to clarify that breast cancer is not a genetic disease per se, and it does not mean that if a parent has breast cancer, the child will definitely get it. It is just that if a woman’s immediate family has breast cancer, the patient’s chances of getting breast cancer themselves will increase significantly. If a lump is found on the top of the breast, ultrasound or mammogram should be done to determine the benignity of the lump. If the lump is suspected to be malignant, that is, if breast cancer is suspected, surgery is needed to remove the lump and send it for pathological examination. If the lump is benign, it is usually more likely to be a fibroadenoma and can be removed simply, or if the lump is small, minimally invasive surgery can be considered.
