Breast Cancer Awareness

Breast cancer is the most common type of cancer in Women. Most women diagnosed with breast cancer are over the age of 50, but younger women can also get breast cancer.

About 1 in 8 women are diagnosed with breast cancer during their lifetime. There’s a good chance of recovery if it’s detected at an early stage. For this reason, it’s vital that women check their breasts regularly for any changes and always have any changes examined by a Doctor.

Breast cancer is a disease in which cells in the breast grow out of control. There are different kinds of breast cancer. The kind of breast cancer depends on which cells in the breast turn into cancer.

Breast cancer can begin in different parts of the breast. A breast is made up of three main parts: lobules, ducts, and connective tissue. The lobules are the glands that produce milk. The ducts are tubes that carry milk to the nipple. The connective tissue (which consists of fibrous and fatty tissue) surrounds and holds everything together. Most breast cancers begin in the ducts or lobules. Breast cancer can spread outside the breast through blood vessels and lymph vessels. When breast cancer spreads to other parts of the body, it is said to have metastasized.

Risk Factors of Breast Cancer

Risk Factors You Cannot Change

  • Getting older. The risk for breast cancer increases with age; most breast cancers are diagnosed after age 50.
  • Genetic mutations. Inherited changes (mutations) to certain genes, such as BRCA1 and BRCA2. Women who have inherited these genetic changes are at higher risk of breast and ovarian cancer.
  • Reproductive history. Early menstrual periods before age 12 and starting menopause after age 55 expose women to hormones longer, raising their risk of getting breast cancer.
  • Having dense breasts. Dense breasts have more connective tissue than fatty tissue, which can sometimes make it hard to see tumors on a mammogram. Women with dense breasts are more likely to get breast cancer.
  • Personal history of breast cancer or certain non-cancerous breast diseases. Women who have had breast cancer are more likely to get breast cancer a second time. Some non-cancerous breast diseases such as atypical hyperplasia or lobular carcinoma in situ are associated with a higher risk of getting breast cancer.
  • Family history of breast or ovarian cancer. A woman’s risk for breast cancer is higher if she has a mother, sister, or daughter (first-degree relative) or multiple family members on either her mother’s or father’s side of the family who have had breast or ovarian cancer. Having a first-degree male relative with breast cancer also raises a woman’s risk.
  • Previous treatment using radiation therapy. Women who had radiation therapy to the chest or breasts (like for treatment of Hodgkin’s lymphoma) before age 30 have a higher risk of getting breast cancer later in life.
  • Women who took the drug diethylstilbestrol (DES), which was given to some pregnant women in the United States between 1940 and 1971 to prevent miscarriage, have a higher risk. Women whose mothers took DES while pregnant with them are also at risk.

Risk Factors You Can Change

  • Not being physically active. Women who are not physically active have a higher risk of getting breast cancer.
  • Being overweight or obese after menopause. Older women who are overweight or obese have a higher risk of getting breast cancer than those at a normal weight.
  • Taking hormones. Some forms of hormone replacement therapy (those that include both estrogen and progesterone) taken during menopause can raise risk for breast cancer when taken for more than five years. Certain oral contraceptives (birth control pills) also have been found to raise breast cancer risk.
  • Reproductive history. Having the first pregnancy after age 30, not breastfeeding, and never having a full-term pregnancy can raise breast cancer risk.
  • Drinking alcohol. Studies show that a woman’s risk for breast cancer increases with the more alcohol she drinks.

Symptoms of Breast Cancer

Different people have different symptoms of breast cancer. Some people do not have any signs or symptoms at all.

Some warning signs of breast cancer are:

  • New lump in the breast or underarm (armpit).
  • Thickening or swelling of part of the breast.
  • Irritation or dimpling of breast skin.
  • Redness or flaky skin in the nipple area or the breast.
  • Pulling in of the nipple or pain in the nipple area.
  • Nipple discharge other than breast milk, including blood.
  • Any change in the size or the shape of the breast.
  • Pain in any area of the breast.

Keep in mind that these symptoms can happen with other conditions that are not cancer.

Types of breast cancer

There are several different types of breast cancer, which develop in different parts of the breast.

Breast cancer is often divided into either:

  • Non-invasive breast cancer (carcinoma in situ) – found in the ducts of the breast (ductal carcinoma in situ, or DCIS) which has not spread into the breast tissue surrounding the ducts. Non-invasive breast cancer is usually found during a mammogram and rarely shows as a breast lump.
  • Invasive breast cancer – where the cancer cells have spread through the lining of the ducts into the surrounding breast tissue. This is the most common type of breast cancer.

Other, less common types of breast cancer include:

  • Invasive (and pre-invasive) lobular breast cancer
  • Inflammatory breast cancer
  • Paget’s disease of the breast

It’s possible for breast cancer to spread to other parts of the body, usually through the blood or the axillary lymph nodes. These are small lymphatic glands that filter bacteria and cells from the mammary gland. If this happens, it’s known as secondary, or metastatic, breast cancer.

Breast cancer screening

Doctors often use additional tests to find or diagnose breast cancer. They may refer women to a breast specialist or a surgeon. This does not mean that she has cancer or that she needs surgery. These doctors are experts in diagnosing breast problems.

  • Breast ultrasound. A machine that uses sound waves to make detailed pictures, called sonograms, of areas inside the breast.
  • Diagnostic mammogram. If you have a problem in your breast, such as lumps, or if an area of the breast looks abnormal on a screening mammogram, doctors may have you get a diagnostic mammogram. This is a more detailed X-ray of the breast.
  • Magnetic resonance imaging (MRI). A kind of body scan that uses a magnet linked to a computer. The MRI scan will make detailed pictures of areas inside the breast.
  • Biopsy. This is a test that removes tissue or fluid from the breast to be looked at under a microscope and do more testing. There are different kinds of biopsies (for example, fine-needle aspiration, core biopsy, or open biopsy).

Treating breast cancer

Breast cancer is treated in several ways. It depends on the kind of breast cancer and how far it has spread. People with breast cancer often get more than one kind of treatment.

  • Surgery. An operation where doctors cut out cancer tissue.
  • Chemotherapy. Using special medicines to shrink or kill the cancer cells. The drugs can be pills you take or medicines given in your veins, or sometimes both.
  • Hormonal therapy. Blocks cancer cells from getting the hormones they need to grow.
  • Biological therapy. Works with your body’s immune system to help it fight cancer cells or to control side effects from other cancer treatments.
  • Radiation therapy. Using high-energy rays (similar to X-rays) to kill the cancer cells.

Doctors from differ different specialties often work together to treat breast cancer. Surgeons are doctors who perform operations. Medical oncologists are doctors who treat cancer with medicine. Radiation oncologists are doctors who treat cancer with radiation.

Living with breast cancer

Being diagnosed with breast cancer can affect daily life in many ways, depending on what stage it’s at and the treatment you will have.

How people cope with the diagnosis and treatment varies from person to person. There are several forms of support available, if you need it.

Forms of support may include:

  • Family and friends, who can be a powerful support system
  • Communicating with other people in the same situation
  • Finding out as much as possible about your condition
  • Not trying to do too much or overexerting yourself
  • Making time for yourself

Preventing breast cancer

As the causes of breast cancer are not fully understood, at the moment it’s not possible to know if it can be prevented. If you have an increased risk of developing the condition, some treatments are available to reduce your risk.

Studies have looked at the link between breast cancer and diet. Although there are no definite conclusions, there are benefits for women who:

  • Maintain a healthy weight
  • Exercise regularly
  • Have a low intake of saturated fat
  • Do not drink alcohol

It’s been suggested that regular exercise can reduce your risk of breast cancer by almost as much as a third. Regular exercise and a healthy lifestyle can also improve the outlook for people affected by breast cancer. 

If you’ve been through the menopause, it’s particularly important that you try to get to, and maintain, a healthy weight. This is because being overweight or obese causes more oestrogen to be produced, which can increase the risk of breast cancer.
