The most common type of invasive breast cancer is known as invasive ductal carcinoma or infiltrating ductal carcinoma (IDC). This type of cancer accounts for 80% of all breast cancer diagnoses.
Invasive ductal carcinoma is a type of cancer that develops when abnormal milk duct lining cells transform and spread into the nearby breast tissue. The cancer cells then begin to spread after that. These cancer cells break into the lymph nodes or bloodstream thus spreading to other organs and areas in the body. This leads to metastatic breast cancer.
Symptoms of common invasive breast cancer include:
To accurately diagnose common invasive breast cancer, several tests may be recommended. These include:
Common invasive breast cancer treatment can be either surgical or conservative (non-surgical).
The exact cause of invasive breast cancer is unknown, but certain risk factors such as age, family history, and hormonal factors can increase the risk of developing the disease.
The most common symptoms of invasive breast cancer include a lump or thickening in the breast tissue, changes in breast size or shape, nipple discharge, and changes in the texture or appearance of the breast skin.
Treatment for invasive breast cancer typically involves surgery to remove the cancerous tissue, followed by radiation therapy, chemotherapy, or hormonal therapy to destroy any remaining cancer cells and prevent recurrence.
In some cases, invasive breast cancer may be hereditary, particularly if there is a family history of the disease or if the patient carries certain genetic mutations such as BRCA1 or BRCA2.
