Breast cancer is the most common cancer among women. Breast cancer is cancer that develops in breast cells. Typically, the cancer forms in either the lobules or the ducts of the breast. Lobules are the glands that produce milk, and ducts are the pathways that bring the milk from the glands to the nipple. Cancer can also occur in the fatty tissue or the fibrous connective tissue within your breast.
Types of breast cancer
There are several types of breast cancer, and they are broken into two main categories: “invasive” and “noninvasive,” or in situ.
These two categories are used to describe the most common types of breast cancer, which include:
Ductal carcinoma in situ: Ductal carcinoma in situ (DCIS) is a noninvasive condition. With DCIS, the cancer cells are confined to the ducts in your breast and haven’t invaded the surrounding breast tissue.
Lobular carcinoma in situ: Lobular carcinoma in situ (LCIS) is cancer that grows in the milk-producing glands of your breast. Like DCIS, the cancer cells haven’t invaded the surrounding tissue.
Invasive ductal carcinoma: Invasive ductal carcinoma (IDC) is the most common type of breast cancer. This type of breast cancer begins in your breast’s milk ducts and then invades nearby tissue in the breast. Once the breast cancer has spread to the tissue outside your milk ducts, it can begin to spread to other nearby organs and tissue.
Invasive lobular carcinoma: Invasive lobular carcinoma (ILC) first develops in your breast’s lobules and has invaded nearby tissue.
Other, less common types of breast cancer include:
Paget disease of the nipple: This type of breast cancer begins in the ducts of the nipple, but as it grows, it begins to affect the skin and areola of the nipple.
Phyllodes tumor: This very rare type of breast cancer grows in the connective tissue of the breast. Most of these tumors are benign, but some are cancerous.
Angiosarcoma: This is cancer that grows on the blood vessels or lymph vessels in the breast.
Here are the following are the major 8 signs of breast cancer:
1. Thickening or lump inside the breast or underarm area
2. Change in the shape and size of the breast
3. Scaly sore, Itchy, or rash on the nipple
4. Nipple discharge that starts suddenly
5. Redness, warmth, swelling or darkening
6. Skin dimpling or puckering
7. Pulling in of your breast or nipple and
8. New pain in only one spot that doesn’t go away
