Most breast cancers begin in the inner lining cells of the ducts that carry milk to the nipple (ductal cancers) or Sometimes start in the glands that make breast milk (lobular cancer).
From a single cancer cell it multiplies and grows bigger and becomes palpable. Once the tumor grows larger it can directly affect the skin over the breast and nipple or invade the chest wall , it can spread along the lymphatics into axillary nodes or through blood into other organs like lungs , bone , liver and brain at a later stages .
No breast cancer at early stages will not produce any pain , only in advanced stages will produce pain.
Breast cancer occurs only in people whose family member has /had cancer or has any risk factors.
No , only 10% breast cancer is hereditary and only 50% of patients with breast cancer will have a identifiable cause and for the others the cause is not known.
Cancer aggravates on doing a biopsy or on surgical removal
No , biopsy must be done in all tumors unless not possible before starting the treatment to confirm the diagnosis. Surgery still remains the main modality and most effective modality for treating most solid tumors and can be done safely and when combined with chemotherapy and radiation therapy gives the best outcome at present.
