Underwear is a personal thing for female friends, and the quality of underwear on the market is also uneven. If the underwear is worn incorrectly, it will cause great harm to the body. Below, Jellyfish will tell you about the dangers of improper wearing of underwear, the early symptoms of breast cancer, and how to prevent breast cancer.
The dangers of improper underwear
1. Underwear cups are too small to affect breast health. Some female friends choose undergarments with smaller covers when choosing underwear. Although this kind of underwear can make the chest look stronger, it will compress the blood vessels and lymphatics in the chest for a long time. It is easy to cause breast disease. In addition, cups that are too small can easily cause paramilk, which also affects breast appearance.
2. The cup is too large, which may cause breast sagging.
A cup that is too large generally does not have a great impact on breast health, but it is not good for the curve of the breast. Long-term wear of underwear with cups that are too large lacks support for the breast, and prone to breast sagging.
3. If the shoulder strap of the underwear is too tight, it will be harmful to the health of the breast. Excessive tightening of the shoulder straps will not only cause shoulder discomfort, but also cause the underwear to move up. If there is a steel support in the underwear, it will compress the breast tissue, which will have an adverse effect over time.
4. Long wearing underwear increases the incidence of breast cancer
Some research data show that women who wear underwear for more than 12 hours will increase the incidence of breast cancer by 75%. Therefore, if you rest at home on weekdays or other non-public places, you can minimize the time to wear bras, which will help prevent breast cancer.
Early symptoms of breast cancer
1.Lump or pain
In fact, a symptom that is more obvious in the early stage is the feeling of pain. In many patients, the first symptom when mastitis occurs is pain. Most of them are single and rare, and the shape is more round, oval or irregular. The texture is generally stiff and unclear; breast cancer with cystic hyperplasia may have pain and dull pain; pain in advanced breast cancer often indicates that the tumor directly invades the nerve.
2. Nipple and areola changes In addition to the painful feeling, in fact, there will be some changes in the nipple and areola. Breast cancer in the central area of ​​the breast, the invasion of large ducts can cause the nipples to flatten, sag, retract, and even fall into the nipples. Causes areola deformation.
3. Women with many skin changes are more afraid of mastitis, so in daily life, we must know which symptoms will occur, so that better treatment can be performed. Skin changes are also a type, often superficial Vein irritation, dimple sign and orange peel skin.
4, axillary lymphadenopathy is rare as the first symptom of breast cancer (unless occult breast cancer). Most of them indicate the progression of breast cancer, and pathological examination can help confirm the diagnosis.
5. Nipple discharge breast cancer with discharge accounts for 1.3-7% of the total breast cancer, and it is more common in ductal cancer and papillary cancer. Bloody discharge is more common, followed by serous, bloody, and watery samples.
How to prevent breast cancer
1. More sun exposure is related to taking vitamin D. More sun exposure can also reduce the incidence of breast cancer, because the skin can synthesize vitamin D only in the sun. American experts say that for most people, 10 to 15 minutes of sun a day is enough, which is enough to maintain the vitamin D that the body needs. However, some experts have suggested that if the skin is exposed to the sun too much, the risk of skin cancer will increase, so it is necessary to stop the sun.
2, weight control exercise can prevent breast cancer, the fundamental reason is that it can control the body to gain weight. A study reported that women who rapidly gain weight after the age of 18 have almost twice the risk of breast cancer after menopause than those who maintain a standard weight for a long time.
3. Don't drink. If you drink alcohol once a day, your risk of breast cancer will increase by 11%. If you drink it twice a day, the risk will be 24%. If you drink more than twice a day, the risk will increase 40%. Therefore, it is recommended that ladies who like drinking alcohol, it is best to drink no more than 3 times a week, and the amount should be limited.
4.Take vitamin D
The latest research results show that vitamin D has the effect of preventing breast cancer. Studies have found that women who take 200 international units of vitamin D (about two teaspoons of vitamin D-containing milk powder per day) can reduce their risk of breast cancer by about 30%. Doctors therefore recommend that women aged 50 years and younger take at least 200 international units of vitamin D per day; women over 50 years old preferably take 400 to 600 international units of vitamin D per day.
Conclusion: If the underwear is too small for a long time, it will cause breast disease. If you wear a large underwear for a long time, it will cause the breast to sag. Wearing underwear for too long can increase the incidence of breast cancer. In life, female friends must choose the right underwear to prevent diseases.
