There are different treatments that can be performed for each of the four types of cancer, and there are also different methods such as chemotherapy after surgery. HER2-positive and triple-negative breast cancers are less frequent than other breast cancers, but they are very aggressive and grow quickly.
*Heterogeneous cancers: Cancers with different genetic origins, properties, and responses to anticancer drugs
*ER: Estrogen receptor
*PR: Progesterone receptor
*HER2: Human epithelial cell proliferation factor receptor type 2. When overexpressed, it is involved in the proliferation or malignancy of cells.
Breast cancer is most common in traumatic chambers* at 50%. This is because there is a lot of breast tissue in the traumatic chamber. In addition, because more breast tissue is usually located in the left breast, the left breast cancer is more likely to develop the disease than the right breast cancer.
*Traumatic chamber: the outer upper part of the breast
The probability of breast cancer is proportional to the amount of breast 'tissue', not the amount of breast 'fat'. People with large breasts usually have a lot of fat in their breasts, so it is difficult to say that a larger breast is more likely to cause breast cancer.
In addition, most of the women under the age of 60 in Korea have dense breasts. In the case of dense breasts, the proportion of breast tissue is higher than breast fat, which increases the risk of breast cancer. Therefore, it is necessary to make self-examination a routine and visit the hospital every year for a check-up as much as possible.
*Dense breasts: When breast tissue is a large proportion of the breast
When does breast cancer occur?
In the case of the time when breast cancer is detected on the image during mammography, that is, when breast cancer is clinically palpable, the cancer is about 1.3~2.4 years old according to textbooks. In addition, many factors are involved in the growth of cells, so the period for a single breast cancer cell to become palpable cancer is 2-3 years.
Nonetheless, it's possible that you were screened a year or two ago and you'll be diagnosed with breast cancer this year.
*Interval cancer: Interval cancer, a cancer that is found between tests because not all cancers grow at the same rate.
The stage of breast cancer is sometimes divided into stages 0~4, but hospitals classify it into three stages as follows.
It is a breast cancer up to 2 cm in size. These include periods 0 and 1.
It is breast cancer with advanced lymph node metastases. Lymph nodes are located throughout the body, but in breast cancer, they usually spread to the lymph nodes in the armpits, collarbones, and between the ribs.
3. M, Metastasis
It is a breast cancer with distant metastases to other organs. It metastasizes a lot, in the order of bones, lungs, liver, and brain.
According to statistics released by the Korean Breast Cancer Society in 2018, the survival rate of untreated breast cancer is 18.0% at 5 years and 3.6% at 10 years. In comparison, the 5-year survival rate for stage 2 patients is 94% and the 10-year survival rate is 84%.
This means that treatment is absolutely necessary. Breast cancer is a cancer with more advanced treatments than any other cancer, including surgery, radiotherapy, chemotherapy, anti-hormones, and targeted therapies, and there are standardized treatments.
The treatment effect is good, so it is necessary to proceed quickly when it is first detected. Among them, chemotherapy and targeted therapy are performed first after surgery if the disease has spread to other organs or is likely to have metastasized.
First of all, if you have a family history of breast cancer, your chances of breast cancer are doubled. But it's not a big deal. However, it is very important to take care of your diet. In fact, the incidence of breast cancer among Korean women living in Korea and Korean women living in the United States is about three times different. This is due to differences in eating habits.
Avoid white flours, processed meats, and fatty foods, eat fresh, seasonal foods that are natural and fresh, and eat steamed or baked foods rather than fried foods.
In addition, you need to adjust your diet so that you don't become obese. This is because female hormones are released from fat after menopause, so obese women are more likely to develop breast cancer.
You can make it a habit to rub your breasts with the palm of your middle. The timing is 3~5 days after the end of menstruation every month. This is because this is when the breasts are at their smallest and softest.
All vitamin-based supplements are available. Among them, there are statistics that vitamin D deficiency increases the risk of breast cancer and has a high recurrence rate, so it is recommended to take vitamin D supplements.
If you are in your 20s, it is recommended that you take it for 5 years and try to get pregnant after taking it for 3 months, and if you are in your late 30s and want to get pregnant, you can try to get pregnant after 3 months after taking it for 2 years
