Breast cancer is cancer that begins in the breast and spreads to other parts of the body. When cells multiply out of control, cancer develops. Breast cancer cells typically form a tumor, which can be seen on x-rays or feel like a lump. Breast cancer affects nearly always women, but it may also affect men.
It's important to remember that the majority of breast lumps are benign and not cancerous (malignant). Breast cancers that aren't cancerous are rare growths that don't develop outside of the breast. While benign breast lumps are not life-threatening, they can raise a woman's risk of developing breast cancer. A health care provider should examine every bump or alteration in the breast to decide whether it is cancerous.
Where breast cancer starts:
Breast cancer may start in a variety of places in the breast. The majority of breast cancers originate in the ducts that transport milk to the nipple (ductal cancers), but some begin in the glands that produce breast milk (lobular cancers) Other forms of breast cancer, such as phyllodes tumor and angiosarcoma, are less common. A small percentage of breast cancers begin in other tissues. Sarcomas and lymphomas are tumors that aren't often thought of as breast cancers.
Many forms of breast cancer can cause a lump in the breast, but not all of them do. Read about the signs and symptoms of breast cancer and how to mention them to the doctor in Breast Cancer Signs and Symptoms. Many breast cancers are often discovered on diagnostic mammograms, which may diagnose cancers at an early date, even before they are felt or signs appear. The chest wall, skin, ducts, areola, nipple, lobules, stroma, ribs, and lymph nodes are included in this diagram of breast anatomy from front and side views.
Types of breast cancer:
Breast cancer comes in multiple forms, the most common of which are ductal carcinoma in situ (DCIS) and invasive carcinoma. Others, such as phyllodes tumors and angiosarcoma, are rare. Breast cancer cells are screened for proteins named estrogen receptors, progesterone receptors, and HER2 after a biopsy. In the lab, the tumor cells are also examined closely to determine the grade. Treatment choices may be influenced by the various proteins identified and the tumor grade.
How breast cancer spreads:
As cancer cells enter the blood or lymph system and are transported to other areas of the body, breast cancer may spread. The lymph system is a network of lymph (or lymphatic) vessels that bind lymph nodes in the body (small bean-shaped collections of immune system cells).
Lymph is a transparent fluid that includes tissue by-products and waste material, as well as immune system cells, within lymph vessels. Lymph fluid is carried out from the breast by lymph vessels. Cancer cells may infiltrate certain lymph vessels and begin to expand in lymph nodes in the case of breast cancer. The majority of the breast lymph vessels flow into:
Lymph nodes under the arm
Around the collarbone, there are lymph glands (supraclavicular [above the collar bone] and infraclavicular [below the collar bone] lymph nodes) near the breastbone, there are lymph nodes within the chest (internal mammary lymph nodes) The supraclavicular, infraclavicular, axillary, and internal mammary lymph nodes are seen in relation to the breast in this diagram.
If cancer cells have spread to your lymph nodes, there's a good risk they've passed through your lymph system and spread to other areas of your body (metastasized). The further lymph nodes that contain breast cancer cells, the more likely cancer will spread to other organs. As a result, having cancer in one or more lymph nodes will have a significant impact on the recovery strategy.
To find out how cancer has advanced, you'll usually need surgery to cut one or two lymph nodes. Despite this, not all women with cancer cells in their lymph nodes develop metastases, and some women who do not have cancer cells in their lymph nodes develop metastases later.
Symptoms of Breast Cancer Breast:
cancer can manifest itself in a variety of ways depending on the individual. The majority of people are completely oblivious to any warnings. A lump in the breast or armpit is the most prominent symptom. Skin shifts, discomfort, a nipple that draws back, and irregular discharge from the nipple are among the other symptoms.
Early Warning Signs of Breast Cancer
Common symptoms of breast cancer include A lump that won't go anywhere in the breast or underarm. This is a common first sign of breast cancer. A tumor on a mammogram will normally be seen by the doctor long before you can notice or sense it.
• Swelling around the armpits or along the collarbone. This may indicate that breast cancer has spread to nearby lymph nodes. Swelling can begin before you see a bump, so tell your doctor if you see anything unusual.
• While lumps don't normally hurt, they can cause pain and tenderness. Some may give you a prickly sensation.
• Your breast has a smooth or indented section. This could occur as a result of a tumor that isn't visible or palpable. Changes in the size, contour, shape, or temperature of the breasts are examples of breast changes.
Changes in the breast, such as the following:
• Draws inward
• there a dimple
• Itches from Burns
• Sores appear
Nipple discharge is unusual. It may be clear, muddy, or a different color altogether. A marble-like area under your skin that is different from the rest of your breasts.Like
