Breast cancer is a condition characterized by uncontrolled cell division in breast tissue. 

Initial symptoms of breast cancer may include

Breast Lump: The formation of a lump in the breast due to the accumulation of cancer cells is a common early sign.

Other signs of breast cancer can include

Breast Swelling: Enlargement of the breast, which can be indicative of breast cancer.

Irritation in the Breast: Persistent irritation, soreness, or discomfort in the breast that doesn't resolve should be evaluated.

Nipple Changes: Changes in the nipples, such as flakiness (a scaly appearance), redness, pain, or discharge other than milk, especially if it's bloody.

Breast Pain or Discomfort: Any pain in the breast area should be a matter of concern, as it can be a potential sign of breast cancer.

It's important to note that these symptoms may or may not be noticeable, which is why regular screening is crucial. Screening is typically done before the symptoms of breast cancer become apparent. While some breast changes can be related to hormonal fluctuations or menopause, persistent and unexplained symptoms should be evaluated, as they could be signs of breast cancer.
