Why cancer early is not easy to be found

Answer: cancer cells in a beginning, because the volume too small can not easily be detected, equal in length to1 cm from the tumor size, usually have brought together one billion cancer cells. Cancer cells from one becomes two, two becomes 4, then doubled to one billion, it will be a long time. Tumors less than 0.5 cm, even the most sophisticated equipment is also very difficult to scan. So often patients was found to be suffering from cancer, cancer cells have much to a certain degree, the body has been showing symptoms, not early cancer.
Therefore, to early detection, must be in physical symptoms before receiving regular screening. For example, colorectal cancer, gastric cancer, breast cancer, cervical cancer, if can in the middle to later checked regularly, can be detected early, the cure rate can reach 90% or more.

Q: what cancer is particularly difficult to be found, why?
Answer: some cancers, such as lung cancer was less likely to be detected early. Each year as a chest X ray film, may this year X light results in normal, but the next year, according to X light is the three period of lung cancer. This is because the tumor before to a certain degree, from a X optical disc is completely invisible. For example, when the tumor is less than a centimeter, tumor has containing one billion cancer cells, but in an X ray and unable to display, but the coming year filming, but found that the tumor had increased to10000000000 cancer cell, lung cancer is the three period. So, even if the annual chest X ray film screening, early detection of lung cancer can not accurately.
In addition to cancer cells require a considerable number can be found, some cancers because life in deep organs, did not see the no touch, no obvious symptoms, including lung cancer, esophagus cancer, liver cancer, ovarian cancer, bladder cancer, pancreatic cancer, kidney cancer,virtual office gallbladder cancer.
Esophageal cancer is clinically diagnosed patients are generally divided into two types, one is completely without symptoms, inadvertently found; another is to eat when feeling difficult swallowing, food will get stuck or some uncomfortable symptoms such as chest stuffy pain and medical treatment, followed by endoscopy revealed a tumor, and then by slicing sampling and confirmed esophageal cancer accounted for nine into. Esophageal cancer patients in the feel of symptoms, tumor have been more than5 cm, the extent of up to three weeks, if no distant metastasis situation exists, can be quite difficult to control cancer.
Early bladder cancer usually has no symptoms, symptoms and is often accompanied by other urological diseases, such as cystitis, prostatitis and stones, so it is easy to be ignored.
Because of the anatomical position of the pancreas ( by gastric cover ), ultrasound is not easy to find. Clinically, many times because of cancer cell invasion and oppression to the duodenum causing jaundice phenomenon is discovered. Sometimes patients with pancreatic cancer will also appear in the urine.
If everyone can always pay attention to changes in body, know more about cancer symptoms may appear, equipped with the right knowledge, to early detection, early diagnosis, early and correct treatment, not only can prevent cancer progression, cure rate is relatively higher than many.
Ask: how to make the most effective prevention?
Answer: in the current80% of cancer could be prevented by to reduce the occurrence of. Therefore, the most basic prevention is the understanding about the living environment of the carcinogenic potential of reason and substance, and try to avoid contact or alert.
The United States Harvard University School of public health, Dr. Ezzati published in 2005report, summed up the nine carcinogenic factors, as long as to avoid contact with, the global cancer deaths can be reduced to 1/ 3 of the above. These nine risk factors, including smoking, drinking, obesity,: fruit and vegetable intake, unsafe sex, lack of exercise, urban air pollution, indoor burning coal pollution, injection needle.
In addition, listen to your body 's signal is also very necessary, effective prevention means. Such as breast cancer,company formation but after the age of 40regular breast ultrasound and breast X optical imaging examination, should also be regular self-examination, such as mass carefully touch can be found. As long as pay more attention to their body, they are able to get early treatment effect.
