In particular, if you feel a crushing sensation in the scrotum, which feels like a cinderblock has been placed inside and lasts for more than a week, you should seek a doctor’s diagnosis immediately. This is the most typical precursor of testicular cancer and requires blood tests and scrotal ultrasound. The most common age group of testicular cancer is 20-39 years old. 3.Bowel and stomach cancer: fatigue can’t be improved no matter how much rest you take Generally speaking, feeling fatigue is a sign that the cancer has progressed, but for leukemia, bowel and stomach cancers, fatigue may be felt at the early stage of the disease. What is the difference between cancer fatigue and ordinary fatigue? Ordinary fatigue will disappear after taking a rest, while cancer fatigue will find it hard to improve no matter how to take a rest. Ovarian cancer: persistent abdominal bloating Many women think that abdominal bloating is extremely common, so they don’t need to make a fuss about it. However, it may be a sign of ovarian cancer.

Breast cancer: both men and women should be alert to breast lumps Breast cancer is not the patent of women, both men and women should actively prevent it. If women find redness and lumps in the breast skin, they should be extra cautious. In particular, if a rash appears on the breasts and does not go away for several weeks, it is important to go for a checkup. In addition, in non-lactating women, nipple depressions and often fluid is a bad sign.

In addition to blood in the stool, bowel cancer may also cause symptoms such as thinner and more frequent stools, or even cause difficulty in passing stools if the tumor grows close to the anus. In addition, the American Cancer Society says that body pain increases with age. But when pain occurs inexplicably in a certain part of the body and lasts for more than a week, the cause should be identified as soon as possible, because pain for no apparent reason may be a sign of cancer. For example, prolonged abdominal pain is a symptom of colorectal cancer, chest pain may be caused by lung cancer, and bone soreness may be a symptom of cancer metastasis. Pancreatic cancer can manifest itself in the epigastric region, such as persistent dull or cramping pain around the umbilicus or in the right upper abdomen, which can be paroxysmal or persistent, and usually worsens gradually, radiating to the lower back.
