I Found a Lump,
is it Cancer?
Not all breast lumps cause cancer. In this section we will discuss the differences between benign and malignant breast lumps.
Benign Breast Lumps
Breast lumps or growths found in breasts are usually not cancerous nor life threatening. If your doctor is suspicious of a lump, he or she may need to do a biopsy to determine if it is malignant. A biopsy is a surgical procedure in which all or part of the tumor is removed. The cells from the tumor are then examined to see if they are benign or malignant.
Some types of benign lumps are:
Both types of growths are not life threatening and cannot spread to other parts of the body. However, such benign conditions may put women at greater risk of developing breast cancer.
Malignant Breast Lumps
Malignant lumps or tumors are cancerous. They have the ability to invade the tissue which surround them. Malignant tumors are classified by grades.
If you can feel the lump in your breast, it may feel hard, or as if your breast is thicker in that spot. If you find a lump before a mammogram, it is very important that you see a healthcare professional to have it further examined. Any lump should be looked at with caution until it is determined if it is benign or malignant.
describe how tumor cells and tissue look under a microscope. It is based on how different a cancer cell looks from a normal, healthy cell, and can indicate how likely the cancer is to spread.
GX (No grade)
The tumor grade cannot be determined.
G1 (Low grade)
Tumor cells and tissue look well differentiated or normal.
G2 (Intermediate grade)
Tumor cells and tissue look moderately well-differentiated or close to normal.
G3 (High Grade)
Tumor cells and tissue look poorly differentiated and do not look normal.
G4 (High Grade)
Tumor cells and tissue have no differentiation and do not look normal.
