You've discovered a lump
If you feel a lump in your breast, try not to panic or worry.
Most lumps are not breast cancer, but something less serious, such as a benign breast condition.
Some lumps will go away on their own. In younger women, lumps are often related to menstrual periods and will go away by the end of the cycle.
However, if you find a lump (or any change in your breast or underarm area), it’s best to see your health care provider to be sure it's not breast cancer.
