Breast cancers are either benign or malignant. Benign tumors include fibrocystic lumps, fibroadenomas, and papillomas. Malignant tumors are life-threatening and can be divided into four types: luminal A, luminal B, HER2 type, and basal type. Treatment options depend on the type and aggressiveness of the cancer.
Although there are different types of breast cancers, they are all classified into two categories. They are either benign breast tumors, meaning they are non-cancerous and not life-threatening, or malignant breast tumors, meaning they are cancerous. The many different types of breast cancers that are discovered are always either benign or malignant.
When a lump is found in the breast, a biopsy is often done to detect any tumors that may need treatment. Most lumps found in the breast end up being benign tumors and usually require no further treatment. They occasionally require surgical removal for the breasts to function normally.
There are three different types of benign breast tumors. The most common non-cancerous breast lumps found inside the breast are called fibrocystic lumps. These lumps can look like small cyst-like bumps and can be painful. When hormones are released from the ovaries during ovulation, an overreaction of the mammary glands or fibrous breast tissue can create these small lumps. Consuming products with caffeine can stimulate the growth of fibrocystic lumps.
Another type of benign breast tumor is called fibroadenomas. These lumps are firm but can roll up inside the breast when pressed with your fingers. They typically occur in younger women under the age of 25 and do not feel held when pushed.
Papillomas are the third type of benign breast tumor. These tumors appear inside the breast ducts near the nipple. They tend to stay very small in size and can cause a nipple discharge that may appear clear or bloody.
Malignant breast tumors are life-threatening. If a cancerous tumor is not found in the breast through routine breast exams, the tumor continues to grow. The malignant tumor will then spread to the lymph nodes and bloodstream, significantly reducing a woman’s chances of survival.
Breast cancer has been divided into four different types of breast cancers. These four different types are called luminal A, luminal B, HER2 type, and basal type. These tumors were named due to their differences in appearance and molecular features.
Luminal A and luminal B tumors tend to grow slowly. Luminal A cancer has a better prognosis than luminal B because luminal B grows slightly faster. Both of these types of breast cancer are estrogen receptor positive.
While the HER2 type of breast cancer grows rapidly and displays extra HER2 genes, undergoing a series of targeted treatments can be quite successful. Basal type breast cancer grows faster than any other type and has the worst prognosis. Several tests may be performed to determine what type of cancer has been found, the aggressiveness of that particular cancer, and which treatment may be the best option with the best prognosis.
