Cancer is one of the most famous incurable diseases. Cancer is a malignant tumor in which chaotic cell reproduction occurs, accompanied by invasion into the underlying tissues and metastasis to distant organs with a flow of lymph or blood. In simple terms, the disease causes cell mutation. Cancer cells do not die in the human body, but accumulate and thereby form a tumor. This can happen in anyone’s body – the disease doesn’t choose victims based on gender or skin color. However, there is one important factor – the general state of the body and immunity, it depends on whether our body can cope with the fight against diseased cells or not.

In most cases, oncology is perceived by patients as a death sentence. But not all cancers lead to death. Some of the sick still get rid of the disease and remember it as a nightmare. However, there are also a large number of deaths.

Doctors distinguish several types of cancer depending on the affected organ. A malignant tumor can be in any human organ, because cancer can be called a group of diseases.

Types of cancer:

  • Melanoma – damage to the skin;
  • Leukemia – education in the hematopoietic system;
  • Carcinoma – damage to the epithelial tissue of an organ;
  • Lymphoma – damage to the lymphatic system;
  • Sarcoma is a malignant tumor in the nervous, connective or supporting tissue of the body.

There are other types of disease, such as teratoma, glioma, choriocarcinoma, blastoma. But they are much rarer than those listed above. But this is their danger – they are not studied so well, so they often lead to death.

A variety of symptoms can indicate the presence of oncology. They also depend on the organ that struck the disease. The list of cancer symptoms is very large, so it is worth understanding this issue in detail.

Bowel cancer symptoms

This is one of the varieties of malignant tumors located on the mucous membrane of the colon. Today, this disease is the second most common in people over 45 years of age. Bowel cancer differs from other oncological diseases in its more severe course, serious complications and poor prognosis. Localization of bowel cancer can be any, since the tumor is formed on the mucous membrane of any part of the intestine.

The main difficulty is the complete absence of acute painful manifestations at the initial stage. Because of this, people are late to discover the presence of the disease, about half of the cases are detected in the later stages.

With bowel cancer, the symptoms in women and men are the same, but they differ for everyone depending on the location of the tumor. The case in which a neoplasm occurs in the ileum, jejunum and duodenum is a rather rare occurrence. In this case, the following symptoms appear:

  • Heartburn;
  • Belching;
  • Nausea;
  • Soreness in any part of the abdomen;
  • Feeling of pressure in the stomach;
  • Staining of feces in a dark color.

  • Violation of the functioning of the intestine;
  • Development of anemia;
  • Cramping pains in the abdomen;

Symptoms of colorectal cancer

Such an ailment develops against the background of a previous chronic disease. People with chronic bowel disease should undergo regular medical examinations. This is required in order to detect the disease in the early stages and avoid complications.
