There are as many as 2.26 million new cases of breast cancer worldwide in 2020. Breast cancer has replaced lung cancer. Beware of enlarged breast nodules that do not hurt. Many women have regular breast color ultrasound examinations. Some people find out that they have breast nodules, so will nodules definitely develop into cancer? How far are breast nodules from breast cancer after all? It also includes benign tumors such as hyperplastic nodules of the breast, breast cysts and breast fibromas. In general, benign breast nodules do not need special treatment, and nodules can be observed regularly. If there is no pain in the nodules, many people think that the nodules will become cancer sooner or later, and the nodules that have been identified as benign nodules will not become cancerous. If the examination indicates that there is a malignant risk of breast nodules, women over the age of 40 will have a routine color ultrasound examination every six months, and the incidence and death rate of lung cancer in China has been on the rise in the past 20 years. According to the statistics of the World Health Organization, the global incidence of lung cancer in 2020 is 2.2 million.

It is the largest cancer in the world. How to prevent it?

Today (4th) is World Cancer Day. According to data released by World Health Organization (WHO) International Cancer Research Institute, there were as many as 2.26 million new cases of breast cancer worldwide in 2020, more than 2.2 million cases of lung cancer. Breast cancer has replaced lung cancer as the largest cancer in the world.

Doctor: beware of enlarged breast nodules that don't hurt!

In China, there are about 420000 new cases of breast cancer every year, the age of onset is earlier than that in western countries, and the peak of incidence is at 45 Mel and 55 years old. With the popularity of physical examination, many women will have regular breast color ultrasound examination. Some people find out that they have breast nodules, so will nodules definitely develop into cancer? How far are breast nodules from breast cancer after all?

Breast nodules, including breast cancer, as well as benign tumors such as breast hyperplastic nodules, breast cysts and breast fibromas. Most of the nodules are benign, especially those that exist for a long time without obvious enlargement. In general, benign breast nodules do not need special treatment and can be reexamined regularly.

Lin Hua, chief physician of Fuxing Hospital affiliated to Capital Medical University: nodules can be observed regularly. If nodules are associated with pain, they are mostly benign, also known as hyperplastic nodules; if nodules are found without pain and nodules are growing, such nodules should be paid close attention to.

Many people think that nodules will become cancer sooner or later, in fact, the nature of nodules will not change, that is, nodules that have been identified as benign nodules will not become cancerous. If the examination indicates that the breast nodule is at risk of malignancy, it needs to be treated as soon as possible.

Doctors suggest that women after the age of 40 should have a routine color ultrasound examination every six months or a molybdenum target once a year. If the family has a genetic history, the offspring may develop the disease 10 years earlier than she does, so early examination, early detection, and early treatment are necessary.

Incidence and mortality of lung cancer in China in recent 20 years

Show an upward trend

According to the statistics of the World Health Organization, the number of cases of lung cancer in the world was 2.2 million in 2020, ranking second among malignant tumors, while the number of deaths caused by lung cancer was 1.8 million, ranking first among malignant tumors.

In China, the incidence and death toll of lung cancer have been on the rise in the past 20 years. For people at high risk of lung cancer such as family history, smoking history and occupational exposure, low-dose spiral CT screening should be carried out regularly.

Doctors say that lung cancer is asymptomatic in the early stage, and once there are symptoms such as cough, expectoration with blood, chest tightness and shortness of breath, fatigue and hoarseness, it means that the patient's condition is relatively late. It is very important to detect lung cancer early.

At present, the treatment of lung cancer is mainly divided into surgical treatment, targeted therapy and immunotherapy. Experts warn that once cancer is diagnosed, you must go to the hospital for standard treatment.

Cheng Ying, vice chairman of the Lung Cancer Committee of the Oncology Branch of the Chinese Medical Association, said:

For lung cancer, first, accurate medical treatment, there are many targeted drugs, there are targets to find targets, targeted selection of different drugs can achieve good results.

Second, multi-disciplinary cooperation, now the new drugs, so that inoperable patients, locally advanced patients after drug treatment, become able to operate. Therefore, through simultaneous radiotherapy and chemotherapy, the overall cure rate can also be improved.
