What Is Breast Cancer Symptoms?

Breast Cancer?

One type of cancer that begins in the breast is breast cancer. It might begin in either one or both breasts.

Cancer develops when cells begin to proliferate uncontrollably. (See What Is Cancer? for further information on how malignancies begin and spread.)

Breast cancer affects nearly primarily women, although men can develop it as well.

It is critical to recognise that the majority of breast lumps are not cancerous (malignant). Breast tumours that are not malignant are abnormal growths that do not spread beyond the breast. Although not life threatening, some benign breast lumps can raise a woman’s chance of developing breast cancer.

Any breast lump or change should be evaluated by a health care specialist to determine if it is benign or malignant (cancer) and whether it may alter your future cancer risk. To learn more, see Non-cancerous Breast Conditions.

Breast Cancer Signs and Symptoms

Your breast health greatly depends on your awareness of how your breasts typically feel and appear. Mammograms do not always detect breast cancer, despite the need of routine screening tests for the disease. This implies that it’s crucial for you to be aware of how your breasts typically feel and appear so that you can notice any changes.

The most typical sign of breast cancer is a new tumour or lump (although most breast lumps are not cancer). Although breast tumours can sometimes be soft, spherical, sensitive, or even painful, they are more likely to be cancer if they are a painless, hard mass with uneven borders.

Other possible symptoms of breast cancer include:

  • Breast enlargement to full or partial (even if no lump is felt)
  • Skin craters (sometimes looking like an orange peel)
  • Breast or nipple discomfort
  • Lipstick pulling back (turning inward)
  • Red, dry, flaky, or thickened nipple or breast skin
  • Blunt discharge (other than breast milk)
  • Lymph nodes beneath the arm or close to the collarbone that are swollen (Sometimes this can be a sign of breast cancer spread even before the original tumour in the breast is large enough to be felt.)

There are several benign (non-cancerous) breast disorders that can also cause similar symptoms. Nevertheless, it’s crucial to get any new breast tumour, lump, or alteration examined by a skilled medical practitioner so the reason may be identified and treated, if necessary.

Keep in mind that frequent breast cancer screenings do not replace understanding what to look for. Breast cancer may frequently be found early, before any symptoms show, thanks to screening mammography. You have a higher chance of receiving effective treatment if breast cancer is discovered early.

Where breast cancer starts

Breast cancers can develop in several regions of the breast.The breast is a gland that sits over the upper ribs and chest muscles. There are two breasts, one on each side, with glands, ducts, and fatty tissue. The breast in women produces and distributes milk to nourish neonates and babies. The quantity of fatty tissue in the breast regulates its size.

 The breast is divided into several sections:

  • The glands that produce breast milk are known as lobules. Cancers that begin here are known as lobular cancers.
  • Ducts are tiny tubes that emerge from the lobules to transport milk to the nipple. This is the most typical location for the onset of breast cancer. Ductal cancers are cancers that start in this location
  • The nipple is a hole in the skin of the breast where the ducts join to form bigger channels that allow milk to exit the breast. The nipple is encircled by a thicker, darker skin called the areola. Paget disease of the breast, a less prevalent kind of breast cancer, can begin in the nipple.
  • The ducts and lobules are held in place by the fat and connective tissue (stroma). The stroma can be the site of phyllodes tumour, a less prevalent kind of breast cancer.
  • Each breast has blood arteries and lymph vessels. Angiosarcoma is a rare kind of breast cancer that begins in the lining of these arteries. The lymphatic system is detailed further down.

A tiny fraction of breast tumours begin in other tissues. These malignancies are known as sarcomas and lymphomas, and they are not commonly associated with breast cancer.

How breast cancer spreads

Breast cancer spreads when cancer cells enter the blood or lymph system and travel to other regions of the body.

The lymph (or lymphatic) system is a part of your body’s immunological system. It is a network of lymph nodes (small bean-sized glands), ducts or veins, and organs that collaborate to collect and transport clear lymph fluid through body tissues to the blood. Inside the lymph channels, the clear lymph fluid includes tissue by-products and waste debris, as well as immune system cells.

Lymphatic vessels are responsible for transporting lymph fluid away from the breast. Cancer cells can enter lymph veins and begin to develop in lymph nodes in the case of breast cancer. The majority of breast lymph arteries flow into:

  • Lymph nodes behind the arm (axillary lymph nodes)
  • There are lymph nodes in the chest, close to the breastbone (internal mammary lymph nodes)
  • Collarbone lymph nodes (supraclavicular [above the collar bone] and infraclavicular [below the collar bone] lymph nodes)

If cancer cells have migrated to your lymph nodes, there is a greater likelihood that they will travel through your lymph system and spread to other regions of your body (metastasize). However, not all women who have cancer cells in their lymph nodes get metastases, and some women who do not have cancer cells in their lymph nodes may acquire metastases later.

Types of breast cancer

There are several forms of breast cancer. The kind is defined by the type of breast cells that are impacted. The majority of breast malignancies are carcinomas. Adenocarcinomas are the most prevalent types of breast cancer, including ductal carcinoma in situ (DCIS) and invasive carcinoma, since the malignancies begin in gland cells in the milk ducts or lobules (milk-producing glands). Other tumours that can occur in the breast, such as angiosarcoma or sarcoma, are not called breast cancer since they begin in distinct cells of the breast.

Breast cancers are also categorised based on the proteins or genes that each malignancy produces. Breast cancer cells are screened after a biopsy for proteins known as oestrogen receptors and progesterone receptors, as well as the HER2 gene or protein. The tumour cells are also extensively examined in the lab to determine their grade. The specific proteins discovered, as well as the tumour grade, can aid in determining the stage of the malignancy and treatment choices.
