Why does breast cancer happen

Introduction Breast cancer arises in the lining cells (epithelium) of the ducts (85%) or lobules (15%) in the glandular tissue of the breast. Initially, the cancerous growth is confined to the duct or lobule (“in situ”) where it generally causes no symptoms and has minimal potential for spread (metastasis). Over time, these in situ (stage 0) cancers may progress and invade the surrounding breast tissue (invasive breast cancer) then spread to the nearby lymph nodes (regional metastasis) or to other organs in the body (distant metastasis). If a woman dies from breast cancer, it is because of widespread metastasis. Breast cancer treatment can be highly effective, especially when the disease is identified early. Treatment of breast cancer often consists of a combination of surgical removal, radiation therapy and medication (hormonal therapy, chemotherapy and/or targeted biological therapy) to treat the microscopic cancer that has spread from the breast tumor through the blood. Such treatment, which can prevent cancer growth and spread, thereby saves lives. Scope of the problem In 2020, there were 2.3 million women diagnosed with breast cancer and 685 000 deaths globally. As of the end of 2020, there were 7.8 million women alive who were diagnosed with breast cancer in the past 5 years, making it the world’s most prevalent cancer. There are more lost disability-adjusted life years (DALYs) by women to breast cancer globally than any other type of cancer. Breast cancer occurs in ...

Age is one of several factors related to the risk of developing breast cancer. As a person gets older, their risk of developing breast cancer increases. According to the Knowing the risk factors for breast cancer can help a person make decisions regarding screening and lifestyle habits. In this article, we look at the link between age and the risk of breast cancer. We also discuss other breast cancer risk factors, as well as the risks and benefits of undergoing regular screening. Share on Pinterest Nico De Pasquale Photography/Getty Images A person’s risk of developing breast cancer increases as they get older. As people age, abnormal changes in their cells are more likely to occur. Breast cancer is most common in females over the age of Based on data from 2012–2016, the median age of diagnosis in females with breast cancer was Although females are more likely to develop breast cancer after they reach the age of 50 years, younger women can also develop this condition. According to the • 1 in 227 (0.44%) for those aged 30 years • 1 in 68 (1.47%) for those aged 40 years • 1 in 42 (2.38%) for those aged 50 years • 1 in 28 (3.56%) for those aged 60 years • 1 in 26 (3.82%) for those aged 70 years The • 1.9% were aged 20–34 years • 8.4% were aged 35–44 years • 20.1% were aged 44–55 years • 25.6% were aged 55–64 years • 24.8% were aged 65–74 years • 13.7% were aged 75–84 years • 5.6% were aged 84 years+ Age is just one risk factor for developing breast cancer. Some other risk fac...

What is breast cancer? Breast cancer is cancer that starts in the breast. It starts when cells in the breast begin to grow out of control. It can start in one or both breasts. Breastcancer cells usually form a tumor that can often be seen on a mammogram or ultrasound or felt as a lump. Breast cancer is most common in women, but Breast cancer cells can spread to other parts of the body and grow there, too. When cancer cells do this, it’s called metastasis. Cancer is named for the place where it starts. So even if breast cancer spreads to the bones (or any other place), it’s still called breast cancer. It’s not called bone cancer unless it starts from cells in the bone. Are there different kinds of breast cancer? There are many Ductal carcinoma in situ or DCIS Invasive breast cancer • Invasive ductal carcinoma (IDC): This is the most common type of breast cancer. It starts in a milk duct of the breast and grows through the wall of the duct into the nearby breast tissue. • Invasive lobular carcinoma (ILC): This type of cancer starts in the milk glands, called lobules, and grows into the nearby breast tissue. Inflammatory breast cancer (IBC) In Because there’s no lump, IBC might not show up on a mammogram. This can make it harder to find IBC early. It’s more likely to spread and is harder to cure than invasive ductal or lobular cancer. Triple-negative breast cancer (TNBC) triple-negative because the cancer cells are missing three kinds of proteins that breast cancers are teste...

A fungating breast tumor is a rare, advanced type of cancer that causes ulcers or infection on the skin of the breast or the surrounding area. A fungating tumor occurs when the mass breaks through the skin. It causes an ulcer or wound to appear, which can be leaky, odorous, and painful. The following article describes what to expect from fungating breast tumors, along with their causes, treatment, and more. Share on Pinterest Irina Polonina/Stocksy A fungating or ulcerating tumor can occur with several types of cancer, including A fungating tumor occurs when the cancer cells penetrate the skin surrounding the breast. The penetration of cancer cells into the skin causes ulcers, a breakdown of the skin, and infections. From primary tumors Primary tumors develop from cancerous breast cells. When a primary tumor becomes ulcerative, it means the breast cancer cells have penetrated the skin and caused the lesions or ulcers to occur. From secondary tumors A secondary tumor develops from metastasized cancer cells, which have spread from a different area of the body. However, a study from The researchers note that small tumors can also cause ulcerations on the skin. Though they suggest further study, they recommend that doctors do not stage smaller tumors as advanced unless absolutely necessary. This is because the smaller-sized tumors often share the characteristics of less advanced cancer. The direct cause of ulceration is that the breast tumor grows to a point where it breaks th...
