Does cancer have any precursors? These 6 signals have already reminded you!

When abnormal symptoms occur in the body, don't be careless. See a doctor in time for early detection and treatment to avoid the harm caused by serious diseases such as cancer.

1. Everyone has cancer cells

But cancer cells are not as terrible as imagined

Many people are scared when they hear "cancer cells". In fact, everyone has cancer cells in their bodies, but they are not as terrible as imagined.

Our body is like a huge "cell kingdom", with a large number of cells dividing and renewing every day. In this process, due to various factors, such as gene mutations and environmental influences, some "rebellious" cancer cells will occasionally be produced.

However, our body has a strong immune system, like a loyal "guard", always monitoring these cancer cells. Once discovered, the immune system will quickly attack and eliminate them, so most of the time, these cancer cells will not cause any trouble.

In addition, it takes a long time from the appearance of cancer cells to the development of cancer. During this period, we have many opportunities to stop it. As long as you maintain a healthy lifestyle, such as a reasonable diet, eat more vegetables and fruits, eat less high-fat and high-salt foods; insist on moderate exercise to enhance the body's immunity; quit smoking and limit alcohol to reduce the harm of harmful substances to the body; and have regular physical examinations, early detection and early treatment, you can kill cancer in the cradle. So, don't be scared by cancer cells, take active prevention, and we can "coexist peacefully" with it.

2. Cancer is not coming quietly!

These 6 signals have long reminded you

Many people talk about cancer and think that cancer is a sudden disaster. In fact, the body often sends out signals before cancer comes, but it is easy to be ignored by us.

The following 6 signals must be taken seriously:

1. Long-term cough and blood in sputum. If the cough lasts for more than three weeks and does not improve after taking medicine, and is accompanied by blood in sputum, especially for long-term smokers, be alert to lung cancer.
2. Unexplained pain in the body. Continuous pain in a certain part of the body, and gradually worsening, such as headache, bone pain, abdominal pain, etc., may be caused by cancer invading nerves or compressing surrounding tissues. For example, bone cancer may cause bone pain in the early stage.
3. Weight loss for no reason. If you don't lose weight deliberately, but your weight drops significantly in a short period of time, it may be that cancer is consuming the body's energy and nutrients.
4. Long-term indigestion and bloating. Frequent bloating, loss of appetite, indigestion, and even nausea and vomiting may be signs of gastrointestinal cancer, such as gastric cancer and colon cancer.
5. Abnormal skin changes. If new moles appear on the skin, or existing moles suddenly increase in size, change color, break and bleed, be careful of melanoma; unexplained itching, erythema, ulcers, etc. on the skin may also be external manifestations of cancer.
6. Unexplained bleeding. For example, if a woman has vaginal bleeding during non-menstrual periods, it may be cervical cancer or endometrial cancer; if there is blood in the stool, it may be colon cancer; hemoptysis may be related to lung cancer.

3. Do these 3 things to prevent cancer

Although cancer is terrible, good prevention can greatly reduce the risk of disease. The following 3 points are critical.

1. Healthy diet: Eat more fresh fruits and vegetables, which are rich in vitamins, minerals and dietary fiber, can enhance immunity and inhibit the growth of cancer cells. Whole grains, beans and other coarse grains are also good choices, which can reduce the intake of refined staple foods. Eat less high-oil, high-salt, high-sugar and processed meats, which are easy to cause obesity and increase the risk of cancer. At the same time, quit smoking and limit alcohol. The harmful substances in tobacco and alcohol metabolites can damage cells and induce cancer.
2. Regular exercise: At least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, jogging, swimming, etc., can also be combined with strength training, such as lifting dumbbells, push-ups, etc. Exercise can promote metabolism, enhance physical fitness, regulate endocrine, and reduce the risk of cancer.
3. Regular physical examination: Different age groups and populations have different focuses on physical examination items. For people over 40 years old, it is recommended to have a gastrointestinal endoscopy once a year to screen for gastrointestinal tumors; women should have regular breast and cervical examinations. Early detection and early treatment can increase the cure rate of cancer.
