What is breast cancer? Breast cancer is one of the most common types of cancer. It affects women and men of all ages, but more than two-thirds of new cases occur in women. The good news is that there is a lot that can be done to prevent breast cancer, and many women diagnosed with it can survive. Breast cancer is one of the most common cancers in the world. It's estimated that around 1 in 8 women will be diagnosed with the disease at some point in their lives. However, breast cancer isn't the only cancer that affects women. There are many types of cancer that can affect both men and women, including lung, skin, and colon cancers. Here, we'll talk about the different types of breast cancer and the signs and symptoms you need to look out for.
Many people think they know what breast cancer is. They think that it's just something that happens to old women. They don't realize that breast cancer can happen to anyone. It's not just something that happens to older women. If you are a young woman, you may have heard about breast cancer. There are many myths surrounding the disease. I'm going to talk to you about breast cancer and the facts behind it. I'll also show you what you can do if you think you might have breast cancer. I'm going to show you why you need to go to the doctor if you think you have breast cancer. I'll also talk to you about the treatment you can get if you think you have breast cancer.

Breast cancer can be detected through a range of different tests. The most important of these is a mammogram. This involves taking a series of x-rays of the breast and nipple area to check for signs of cancer. Other tests include ultrasound, needle biopsy, and breast self-examination. The most common treatment for breast cancer is surgery, which can be either a lumpectomy (removal of the tumor) or a mastectomy (complete removal of the breast). Radiation therapy, chemotherapy, and hormone therapy can also be used.
Breast cancer is a type of cancer that arises from the tissues of the breast, including the lining of milk ducts, glands that produce milk or other substances, and lymph nodes. It can also arise from other parts of the body and spread to the breast via lymphatic drainage. Breast cancer may be localized in a part of one breast or may have spread to opposite sides or opposite breasts before being diagnosed. Breast cancer usually begins in cells that have been programmed with instructions contained within tumor suppressor genes for growth and division. In most cases, however, it is these cancer cells that trigger the growth and spread of the tumor, as they continue to divide and grow through a series of steps.
For most women, breast cancer does not spread beyond the breast and is usually cured by the removal of the lymph nodes and other tissues in which it has originated. Most women survive five years after breast cancer diagnosis (for localized disease) and ten years after diagnosis (for advanced disease). Treatment may include surgical removal of tumors; medication; radiation; or a combination thereof. Breast cancer accounts for about 30 percent of all cancers in U.S. women (and 20 percent worldwide), but less than 1 percent of these cases require treatment with systemic chemotherapy (drugs that work throughout the body).s, these growth instructions are found on chromosomes 17, 13, and 18.
Breast cancer is common. The American Cancer Society estimated that in 2012, around 50,700 new diagnoses of invasive breast cancer will be made in the United States. About 51,000 women will die from the disease that year. Because breast cancer is so common, statistics of its occurrence may be very difficult to interpret because they are based on estimates rather than actual counts.
What causes breast cancer?
Breast cancer is the most common cancer in women, and it’s been on the rise over the last several decades. Most breast cancers are found in the cells lining the inside of the milk ducts and lobes. This cancer is often associated with estrogen, a sex hormone produced by the ovaries and adrenal glands. However, studies show that the vast majority of breast cancers do not have any identifiable cause, or that they have more than one cause.
The cause of breast cancer is not known. It can happen for many reasons, including genetics and lifestyle choices. Some studies have suggested an increased risk among women who have ever used hormone replacement therapy (also called hormone therapy or HRT) after menopause (postmenopausal hormonotherapy use). For women who have had breast cancer in one breast, the risk of developing cancer in the other breast is higher than average. This condition is called "sporadic," and happens when the abnormal cells develop in different locations within the breast. It has not been discovered what causes sporadic breast cancer.
According to the American Cancer Society, the factors that increase an individual's risk for developing breast cancer are:
AGE is one of the most important risk factors. An increasing number of breast cancers are diagnosed in young women and older women. The median age at diagnosis of breast cancer has been steadily increasing over time, from 65 years in the 1970s to nearly 70 years in 2000. This increase is due both to an actual increase in incidence rates and a greater likelihood that a woman will be diagnosed with breast cancer as she ages – a phenomenon known as "lead-time bias" – since screening technologies, such as mammography, has been readily available only since the 1980s.
CURRENT AGE is the most important risk factor, but the risk increases with age. Women in their 50s are 1.5 times more likely to develop breast cancer than women in their 40s; women in their 60s are twice as likely, and women in their 70s are three times more likely. For this reason, breast cancer research has focused on the role of estrogens (female hormones).
Hereditary factors play a role in the development of breast cancer. Inherited breast cancers account for about 10–15% of all cases diagnosed each year and for about one-half of all cases diagnosed before age 45 years old. Family history is a very strong indicator of a woman's risk for breast cancer. Approximately 25% of women with breast cancer have a close relative who also had breast cancer. Age is the most important risk factor for this type of breast cancer, but heredity can be an additional risk factor in early-onset disease.
Most women with a family history of breast cancer will not develop the disease themselves, and the specific gene variants responsible for familial breast cancers have not been identified. These gene variants do not change the way that most cases of breast cancer start and progress, and they do not affect treatment options...
The presence of breast cancer in a mother's family is associated with an increased risk of developing breast cancer later in life, but this increased risk does not apply to the development of any specific type of breast cancer or to all forms of breast cancer. The association is not entirely consistent, and it varies depending upon the region, tumor type, and other factors. Women who have a strong family history should consider discussing this information with their doctor.
LIFESTYLE AND HISTORY OF PRACTICE are important risk factors because these can affect hormones that cause changes in cell growth or other processes that lead to the development of breast tumors...
In conclusion, breast cancer is a very common disease in women, but it can be prevented by early detection and treatment. Breast self-examination (BSE) can be helpful but does not replace regular medical exams. Women should be aware that having a mammogram, a screening test, every two years can reduce the risk of dying from breast cancer by about 50%...We know that breast cancer develops in the cells of the breast and that the risk for developing breast cancer is influenced by age, family history, and lifestyle factors... THE FOCUS So let's look at the big picture. If you don't have any personal or family history of breast cancer, your risk is relatively low. But if you have a close relative with breast cancer, or if you're in your 40s, 50s, or 60s, your risk is significantly higher. And if you're over the age of 70, your risk goes up even more. But there are also environmental risks. For example, drinking alcohol increases the risk of breast cancer by as much as 40 percent. So if you're a drinker, you're not just putting yourself at increased risk, you're also putting your family at risk. Of course, there's no way to completely eliminate your risk of developing breast cancer. You can't control what your genes are. But there are things you can do to lower your risk. For instance, getting regular mammograms lowers your risk of breast cancer by 30 percent. And since your risk of getting breast cancer goes up with age, the earlier you start, the better off you'll be.
