Causes of Breast Cancer

Cancer begins when healthy cells in the breast change and grow uncontrollably, forming a mass or sheet of cells called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. A benign tumor means the tumor can grow but will not spread. Breast cancer spreads when the cancer grows into other parts of the body or when breast cancer cells move to other parts of the body through the blood or lymph vessels. As per a study, about one in eight women are diagnosed with breast cancer during their lifetime. There would be a good chance of recovery if it were detected in its early stages.

The actual causes of Breast Cancer are not entirely known. But doctors believe that it occurs when some breast cells start growing abnormally. These cells divide more rapidly than healthy cells do and continue to accumulate, forming a lump or mass. The cells may spread through your breast to your lymph nodes or the other parts of your body. Also, based on the research, Breast Cancer is the result of several factors that include genetics, hormonal, lifestyle and environmental factors, etc. Know the early signs of breast cancer in women from the below sections of this article.

Risk Factors for Breast Cancer

A risk factor is something that may increase the chance of getting a disease. The risk factors of Breast cancer is anything that makes it more possible you will get breast cancer. But having one or more risk factors doesn’t mean that you will develop breast cancer. Because most of the women who develop breast cancer have no known risk factors other than simply being women and growing older. Women are much more likely to develop this cancer than men. Since the etiology of cancer is not yet known completely, factors given below may increase the risk of the disease.

Getting Older

The risk of breast cancer increases as we age. Most of the breast cancer cases diagnosed in women are those who have reached their menopause, i.e., over 50 years. It means that all women between the age group of 50 and 70 years should be screened every three years. Women over the age of 70 are also likely to get breast cancer and may need regular screening.

Your Family History

Women who have a close relative or their mother or sister with breast cancer or ovarian cancer have a higher risk of developing breast cancer. Genes are also one of the major causes of Breast Cancer. Although most of them are not hereditary, there are some genes that determine the likelihood of getting breast cancer. Women who carry the genes like BRCA1 and BRCA2 are at a higher risk of developing both breast and ovarian cancer. Some other genes that may increase the breast cancer are TP53, P53, P65, and ATM. Also, women who had breast cancer earlier are more likely to get breast cancer to the other or the same breast again.

Having first child at Older age

Women who give birth to their first child after 30 years may have an increased risk of breast cancer. Also, women who have never been pregnant will have a greater risk of breast cancer than those who had one or more pregnancies.

Exposure to Radiation

If you have undergone any radiation treatments to your chest as a child or young adult, your risk of breast cancer is increased. Undergoing X-rays and CT scans may raise one’s risk of developing breast cancer.

Height

Taller women (5’8″ or more) are more likely to develop breast cancer than those who are shorter than average. This may be due to interactions between genes, hormones, and nutrition. But the exact reason behind is unknown.

Risk Factors of Breast Cancer
Breast Cancer Risk Factors
Breast Density

A normal breast contains lobules that produce milk and ducts that carry it. This glandular tissue contains a higher concentration of breast cells than other breast tissue and thus makes the breast dense. Also, Women with more dense breast tissue have a greater chance of developing breast cancer because there are more cells that can become cancerous. Younger women tend to have denser breasts and with age the glandular tissue in the breast decreases and is replaced by fat reducing its density.

Estrogen Exposure

Women who started having periods earlier, i.e., before 12 years or entered menopause later than usual have a higher risk of developing breast cancer. The reason is that their bodies have been exposed to estrogen for longer. Estrogen exposure begins when your periods start and drops dramatically during the menopause. In the same way, women not having children, or having children later in life are also at risk of getting this disease as the exposure to estrogen is uninterrupted by pregnancy.

Previous Benign Breast Tumors

Having previous benign breast tumors are also one of the causes of Breast Cancer. Usually a benign or non-cancerous lump in the breast do not indicate breast cancer. However, some of the benign breast changes may lead to breast cancer. This includes Atypical ductal hyperplasia and lobular carcinoma in situ.

Being Overweight

Being overweight or obese after menopause causes more estrogen to be produced. Hence, If you are obese at your menopause stage, then you may be more at risk of developing breast cancer.

Drinking alcohol

Drinking alcohol beyond the limit is also one of the causes of Breast cancer. The more alcohol a woman consumes, the higher her risk of developing breast cancer is. So if you want to drink alcohol, try to limit it to 1 per day.
