Breast cancer and women's health Breast cancer is defined as "a group of solid malignant tumors that originate in the tissues of the breast" (Sarah Crawford, Richard Alder, 2013) in humans and other mammals. It can happen to both men and women. For women, breast cancer is a leading cause of cancer death. According to the National Cancer Institute, in the United States, the estimated new cases and deaths of women from breast cancer in 2014 are 232,670 and 40,000, respectively. For men there are 430 deaths out of 2,360 new cases. From these numbers we can see that women in the United States are very affected by breast cancer, so it is not difficult to imagine the impact worldwide. Although these numbers seem scary, people can actually survive breast cancer if it is detected early and treated properly, so it is extremely important for all of us, especially women, to have a better understanding of breast cancer. Causes Usually, normal cells die when they are old or damaged, newly grown cells will replace them. However, if something goes wrong, there may be too many new cells when the body only needs a few, and the body cannot get rid of the old cells, but accumulates a mass of tissue called a tumor. There are two types of cancer, initial or malignant. Early tumors are usually not harmful to the human body, however, malignant tumors could be life-threatening. These types of tumors will invade surrounding organs and tissues, travel through blood or lymph vessels, attach to other tissues and destroy them. Malignant tumors originate in breast tissues and cause breast cancer. There are two functional tissues in the breast: the lobes and the ducts. Milk is produced in lobules within the lobes and then travels to the nipples through the ducts. About 80%… half of the paper… learned a lot about breast cancer, I think prevention and early detection are key. First, we need to know more, information can be found on the National Cancer Institute website and in many medical journals. It is important to periodically do a self-examination. By identifying risk factors, we will be able to take preventative measures accordingly. If breast cancer occurs, we must remain calm and take the necessary measures. If tissues need to be removed, they should be. Many women show a lack of confidence after major surgery because they don't have real breasts. This situation must be changed. Angelina Jolie, the celebrity, had the courage to choose to remove breast tissue. She believes the results of breast reconstruction can be wonderful, as should the rest of us. Additionally, family support during treatment will make a huge difference.
