Doctors have named the three most aggressive cancers that give off one common symptom

Some types of oncology, as practice shows, it is easier to detect at an early stage than others. Among the latter - and especially aggressive types of cancer, reports Pronews with reference to experts.

For example, skin cancer, if the patient does not ignore a number of external manifestations (bumps on the body, changes in moles and so on), quite often recognized at the first stages.

Among the types of oncology that are particularly difficult to detect, foreign doctors named pancreatic cancer, ovarian cancer and here also included intestinal cancer.

In all cases, the disease can masquerade as less dangerous diseases. For example, in malignant lesions of the pancreas, the ailment is sometimes written off as diabetes. With tumors in the intestine and ovarian cancer symptoms are taken for digestive problems.

Meanwhile, the development of all these types of oncology is often accompanied by symptoms associated with impaired intestinal function. Patients complain of bloating, constipation or diarrhea. This is worth paying attention to.

Also, doctors reminded that when developing oncology, patients in many cases experience weight loss.

Earlier, a specialist in cancer genetics of the Cancer Center at the University of California, Dr. Beth Karlan noted that the key to early detection of cancer is genetics. It sometimes determines the success of treatment, said the specialist.

Karlan gave an example: after one and the same operation, one patient lives only two years, and another - about 20 years.
