There are several kinds of breast cancer. Many of them share symptoms similar to the other.
Ductal carcinoma in situ
This is a precursor of a type of breast cancer that begins in your ducts and is the most common type of breast cancer. This means you have cancer in the cells that line your ducts, but it hasn’t spread into nearby tissue. This type of condition may not show any symptoms, although sometimes it may cause a breast lump or bloody nipple discharge.
Lobular carcinoma in situ
This is not a cancer but a marker for increased risk of breast cancer in the future. It usually has no symptoms and only diagnosed during breast biopsies for other lumps in the breast.
Invasive breast cancer
Breast cancer cells that spread from where it began into the surrounding tissues is referred as invasive or infiltrating. You may notice a lump in your breast or armpit which tends to feel hard and less mobile. It is normally painless. It may or may not be stuck to the underlying skin. You may also notice that one of your breasts look different from the other, and experience swelling or pain in one spot. Your skin may be sore and you may experience a rash or skin that is thick, red or dimpled like an orange.
Metastatic breast cancer
Metastatic breast cancer is advanced breast cancer that spread to other parts of your body, including other organs. Symptoms include, pain in the bones, muscle weakness, headache and nausea, trouble breathing, changes in brain function, belly swelling, loss of appetite which leads to weight loss, yellow skin or eyes (jaundice)
Triple-negative breast cancer
Breast cancer is called triple-negative if it doesn’t have receptors for the hormones estrogen and progesterone and doesn’t make a lot of a protein called HER2. Triple-negative breast cancer tends to grow and spread faster than other types and its tumors make up 10% to 15% of breast cancers. They cause the same symptoms as other common types.
Male breast cancer
About 1% of breast cancers happen in men. As such, men too need to watch out for symptoms such as a lump or thick spot in your breast or armpit. Any changes in the skin of your breast or nipple, such as redness, puckering, scales, or discharge, should not be disregarded.
Paget’s disease of the breast
Paget’s disease often happens along with ductal carcinoma. It affects the skin of your nipple and areola which may be scaly, and red. You may also experience bloody or yellow discharge from the nipple that looks flat or inverted. You may also feel burning or itching in your breasts.
Inflammatory breast cancer (IBC)
Inflammatory breast cancer is a rare type of breast cancer that causes symptoms similar to an infection. The breast feels warm, swollen, and red with skin that is dimpled, leathery, or ridged. You may also notice that your nipple turns inward and experience unusual nipple discharge.
