Breast Cancer

Breast cancer is a condition in which the cells of the breast grow uncontrollably.  Cancer cells that go unnoticed often infiltrate healthy breast tissue and move to lymph nodes beneath the arms. The lymph nodes are a major route for cancer cells to spread to all other areas of the body. Breast cancer is also said to have metastasized when it extends to other areas of the body. For better understanding and development of the imaging and procedural skills, one can train on ultrasound-guided fine needle biopsy of Breast Cancer phantoms. 

Additional Information-I

Lobules, ducts, and connective tissue are the three main components of a breast. The glands that contain milk are known as lobules. The ducts are channels that transfer milk from the breast to the nipple. All are bound together by connective tissue, which is composed of fibrous and fatty tissue. It usually starts in the ducts or lobules.

There are several types of breast cancer. The type of breast cancer is defined by which breast cells become cancerous.

• Invasive ductal carcinoma: The cancer cells spread to other areas of the breast tissue from ducts of the breast. Invasive cancer cells can indeed migrate to other parts of the body
• Invasive lobular carcinoma. Cancer cells migrate from the lobules to the nearby breast tissues. These invasive cancer cells have the potential to spread throughout the body.

To know more about what kind of cancer a patient is having, various molecular level or DNA level tests are performed like, HER-2 DNA detection kit from Abbott or HER2 diagnostic kit from Dako.

Additional Information-II

• Ductal carcinoma in situ (DCIS): It’s a form of breast disease that can increase the risk of cancer. The cancer cells have still grown to the duct lining but have not spread to other breast tissues.
• Paget’s disease of the nipple:  The areola, the thin skin around your nipple, is affected by this kind of breast cancer.
• Phyllodes tumours of the breast: These uncommon tumours form a leaf-like pattern as they develop. They multiply rapidly but rarely spread beyond the breast.

Breast Cancer Stages

• Early-stage, stage 0, or noninvasive:  There are no signs that the disease has spread to the lymph nodes since it is just limited to the breast.
• Stage I: The cancer is less than or equal to 2 centimetres in diameter and hasn’t expanded to other tissues
• Stage IIA breast cancer. The tumour is:
  • Less than 2 centimetres in diameter, with lymph node involvement under the arm.
  • Greater than 2 centimetres in diameter but less than 5 centimetres in diameter, with no lymph node involvement.
• Stage IIB breast cancer. A tumour that is
  • Greater than 5 centimetres in diameter, with no contribution of underarm lymph nodes.
  • Lymph node involvement, larger than 2 but less than 5 centimetres across.
• Breast cancer in stage IIIA or locally advanced breast cancer:
  • A tumour that has spread to lymph nodes under the arm or near the breastbone and is greater than 5 centimetres.
  • Any tumour with cancerous lymph nodes that adhere to one another or surrounding tissue.
• Breast cancer in stage IIIB: A tumour that has spread to the skin or chest wall.
• Breast cancer in stage IIIC:  Any tumour that has spread to more lymph nodes and has spread to a larger scale.
• Stage IV (metastatic): A tumour that has migrated beyond the breast to other organs or tissues, such as the bones, lungs, liver, brain, or distant lymph nodes, regardless of size.

Signs and Symptoms

• Lump formation in the breast
• Part of the breast swells or stiffens.
• Breast tissue with holes or irritation.
• There is redness or scaly skin in the nipple or breast region.
• Discomfort in the region of the breast.
• Blood can be present in the nipple discharge.
• The size or shape of the breasts can change.
• Breast ache.

Risk Factors (Factors that enhances the chances of cancer)

• Mutations in the genes that enhance the risk of cancer
• Breasts that are dense (More Connective tissues)
• Had past Breast cancer or any non-cancerous breast diseases.
• Breast or ovarian cancer in the family
• Had Radiation therapy
• Taking Diethylstilbestrol(DES)
• After menopause, being overweight or obese is a common cause
• Hormone therapy

Conclusion

Breast Cancer is the most frequent cancer among women, with 2.5 million women diagnosed each year. As previously stated, there are many different types of breast cancer, which always encouraged new developments in breast cancer detection, such as the use of AI-powered technologies to help clinicians detect it more accurately. Furthermore, regardless of its stage of progression, it can be treated and eliminated from the body if caught early.
