8 types of deadly cancers actually have this precursor

How to detect the signs of tumors early? The British Journal of General Practice published the latest research from Keele University in the UK. Through the analysis of 25 cancer studies in the UK, the US, the Netherlands and other countries, the following "8 key signals of cancer" were summarized, hoping that everyone will be alerted.

1. Dysphagia

Prediction: Esophageal cancer Comment: Difficulty in swallowing caused by esophageal tumors is mostly manifested as eating dry food and being unable to swallow it, which requires drinking water. At the same time, some people will experience pain behind the sternum when eating.

2. Iron deficiency anemia

Prediction: Colon cancer Comment: If the girl is young, menstruation or dieting can also lead to iron deficiency anemia, and the possibility of colon cancer is small. If it occurs in middle-aged or elderly people, it is best to do a fecal occult blood test.

3. Rectal bleeding

Indication: Senile colorectal cancer Comment: Rectal bleeding is blood in the stool. Blood in the stool must be distinguished from hemorrhoids. Hemorrhoids cause blood in the stool, while tumors cause mixed blood in the stool. In fact, the most obvious symptom of rectal tumor is very thin stool because the tumor is blocking it.

4. Rectal examination may show cancer

Prediction: Prostate cancer Comment: If rectal examination shows cancer, it is too late. It is recommended that men over 50 years old have a PSA test during their physical examination.

5. Blood in urine

Prediction: Urinary tract cancer Comment: Urinary tract cancer mainly refers to bladder tumors. If there is blood in the urine and it is not painful, you should be careful.

6. Coughing up blood

Indication: Lung cancer Comment: Young people coughing up blood is mostly tuberculosis. For older people, if there is blood in the sputum or dry cough with blood after excluding bronchiectasis, an X-ray examination should be taken. Coughing up blood may be a sign of advanced cancer. It is recommended that people over 40 years old who smoke a pack of cigarettes a day and have been smoking for more than 20 years should have regular X-ray examinations.

7. Postmenopausal bleeding

Indication: Gynecological-related cancers Comment: For postmenopausal bleeding, you should first check whether you are taking drugs and health products containing female hormones, such as progesterone, estrogen, etc., especially some health products that claim to restore youth. Get a gynecological examination promptly and don't delay.

8. Breast lumps

Prediction: Breast cancer Comment: Girls who have passed puberty can perform breast self-examination at ordinary times, and go to the hospital in time if they find hard lumps to rule out the possibility of breast hyperplasia. If you have nipple discharge or your skin appears orange peel-like, be careful about breast cancer. In the face of the unfortunate arrival of cancer, adjust your state as soon as possible, get rid of negative emotions such as pessimism and despair, live and treat your life with a calm and happy attitude, fight cancer with the belief that you will win, do not be impatient for success, and be prepared for a protracted war and long-term treatment until cancer is completely defeated.
