Breast cancer most often begins with cells in the milk-producing ducts (invasive ductal carcinoma). Breast cancer may also begin in the glandular tissue called lobules (invasive lobular carcinoma) or in other cells or tissue within the breast.
Just so, which quadrant of the breast is most common for cancer?
The upper outer quadrant is the most common site of origin of breast cancer (38.5%), followed by the central area (29%), the upper inner quadrant (14.2%), the lower outer quadrant (8.8%) and the lower inner quadrant (5%). Breast cancer is more common in the left than in the right breast (16).
What is the most common site for breast cancer?
Invasive ductal carcinoma (IDC), sometimes called infiltrating ductal carcinoma, is the most common type of breast cancer. About 80% of all breast cancers are invasive ductal carcinomas. Invasive means that the cancer has “invaded” or spread to the surrounding breast tissues.
What is the most common site of breast cancer metastasis?
Distant metastases are the cause of about 90% of deaths due to breast cancer. Breast cancer can metastasize anywhere in body but primarily metastasizes to the bone, lungs, regional lymph nodes, liver and brain, with the most common site being the bone.
