Self-examination every month over the age of 30...3 causes of increase in incidence

The cause, treatment, and prevention of breast cancer were summarized with the help of Professor Cheon Jong-ho of Surgery at Boramae Hospital in Seoul, Seoul, which operates Seoul National University Hospital.
Professor Cheon Jong-ho said, `Broth cancer is a very important topic for us. In particular, it is one of the diseases that women often experience, and early detection has a decisive effect on prognosis. But many people have misinformation or misconceptions about breast cancer, which leads to unnecessary fears."
◇Rub Organization
We often think of a woman's chest when we think of 'bubble'. However, the breast does not mean just the breast of a woman, but it is a complex organ made up of various tissues. The most important of them is the wired organization. In the mammary gland, milk is produced, and it is discharged to the nipple through the duct. The duct is a round, cloud-like structure and is connected to the wired line.
There is no problem when the cells in the walls of the normal duct are well organized. But if these cells start to grow abnormally, they can develop into breast cancer.

If you look into the normal duct, the cells are arranged neatly. But when breast cancer occurs, cells grow crushed or disorderly. If the modified cells are converted into cancer cells through atypicality and then confined to the duct, this is called endothelial cancer or stage 0 breast cancer. If cancer cells break through the duct and start to grow into surrounding tissue, they become invasive duct cancer, which corresponds to the stage 1, 2, and 3 breast cancer we know. From this point on, cancer is more likely to spread to other organs.
◇The metastasis process of breast cancer
Fast cancer becomes larger as it invades surrounding tissue, and can especially metastasize to armpit lymph nodes. Lymph nodes are distributed in different parts of the body, and cancer cells can spread to other sites through this pathway. If metastasis occurs to the armpit lymph nodes, the cancer is more likely to spread and the stage of breast cancer is higher.
But you don't have to worry too much. Even if it metastasizes to armpit lymph nodes, it can be treated through surgery or radiation therapy. However, it is important to remember that early detection and treatment of breast cancer is essential because the survival rate is significantly lower when the cancer spreads to other organs.
◇Causes of increase in breast cancer incidence
There are several reasons for the recent increase in breast cancer patients. First, lifestyle changes. In the past, women often married at a young age and had many children, but now the marriage age tends to be delayed, not giving birth, or the number of children tends to decrease. As fertility is low and the risk of breast cancer increases if breastfeeding is not breastfeeding, these changes can increase the risk of breast cancer.
Second, obesity is also an important risk factor. Obesity increases the activity of an enzyme called 'Aromatase', which stimulates the secretion of female hormones, increasing the risk of breast cancer. Breast cancer is closely related to female hormones, and therefore, as obesity increases hormone stimulation in the body, which can increase the risk of breast cancer.
Third, irregular eating habits, lack of exercise, and excessive drinking are also cited as reasons for increasing the risk of breast cancer. Korea has a higher incidence of premenopausal breast cancer than the West (especially in their 40s and 50s), and this age group is gradually on the rise, and following westernized eating habits is considered one of the main reasons.

Although breast cancer can occur regardless of age, it is common in Korea, especially in the late 40s and early 50s. It is important to have regular breast cancer checkups because this is a time when changes in female hormones are clearly seen.
Also, if there is a genetic factor, for example, if a mother or sister has breast cancer, the risk may be higher. In this case, breast cancer can occur even at a younger age, so regular checkups are more important. However, hereditary breast cancer accounts for only 5-10% of all breast cancer, so you don't have to worry too much just because you have a family history.
Breast cancer can occur, although it is rare among women in their late twenties and early thirties. This age group has a relatively low probability of developing breast cancer, but it is recommended to consult an expert immediately if the lump is touched through self-examination or if there is an abnormality in the breast skin.

The most important point of breast cancer is early detection. The earlier breast cancer is detected, the higher the survival rate. Regular breast examinations and self-examinations are essential for early detection, and many people think that there is no way that they will get breast cancer, but breast cancer can occur regardless of age. People in their 20s or 30s are no exception. Therefore, if you feel a little strange, you should get tested right away.
In Korea, it is recommended that self-examination of the breast should be performed every month for those over 30 years of age, clinical examination by a doctor every two years for those over 35 years of age, and breast cancer screening using mammography every two years for women over 40 years of age.
Breast cancer is a disease with a very high survival rate compared to other carcinomas, and it can be treated with a high probability, especially if it is detected early. Treatment methods include surgery, radiation therapy, chemotherapy, and anti-hormone therapy, and customized treatment is performed according to the progression of cancer and the patient's condition.
Let's wrap this up
Professor Chun Jong-ho said "Farrow cancer is no longer 'fear disease'. Early detection and regular checkups can provide treatment close to cure. The important thing is to observe your body well and seek professional counseling immediately if you feel any abnormalities. Interest and practice can protect us rather than worry,' he said.
