What is Cancer ?
What is Cancer ? Tumors developing in the human body (tissues and organs); It can be benign (benign) or malignant (malignant). According to the malignant neoplasms the malignant tumors originate; Cancer (which takes its source from epithelial cells) or sarcoma (which takes its source from mesenchymal cells).
Tumorsare generally round, bordering, capsule-sized masses that can be easily moved. It’s mostly hard on the consistency. However, some tumors can be felt as elastic or soft. Selim tumors develop by pushing the surrounding tissues and during this development they do not invade the surrounding tissues. They do not spread to distant tissues and organs. If these tumors are completely removed with their capsules; They do not develop again in the same place, that is, they do not recur.
The consistency of malignant tumors is very stiff and the borders are often irregular. They are fast-growing formations. However, the rate of development of each tumor is different. Malignant tumors do not have a real capsule. Another characteristic of malignant tumors is their spread. This spread; (Metastasis) in the form of invasion of neighboring tissues into local or distant tissues. The malignant tumor cells may be transported to distant tissues and organs via blood vessels or lymphatic channels, causing new tumor masses (metastatic tumor) to develop there. Metastases; Lung, liver and lymph glands.
What is Cancer ?
Cancer; Is an ill-natured disease that results in uncontrolled and irregular growth of some abnormal cells that appear in an organ or tissue of the body. These proliferating cells (cancer cells) come together and form a mass called a tumor.

Normal body cells grow in an order, multiply and multiply and die. In the early stages of life, normal cells multiply rapidly by the time they complete their development. Once development is complete, normal cells will only divide and multiply in order to replace the worn or dying cells or to perform repair work in trauma. However, as cancer cells continue to multiply, tumor masses also grow constantly. Cancer cells invade the surrounding tissues and destroy it. It also spreads into the blood and lymph, spreading to other parts of the body and causing new tumor foci to form. These tumor foci, which occur in other tissues and organs, are called “metastases”. Here, cancer cells continue to multiply and tumor foci grow.

Although leukemia is a form of cancer, it usually does not form tumors. Instead, cancer cells keep blood and blood-forming organs (bone marrow, lymphatic system and spleen).
Cancer is named according to the body part and microscopic appearance of the source. For example: breast cancer, lung cancer, skin cancer, stomach cancer. Different types of cancer have different rates of growth, spreading patterns and responses to different treatments. For this reason, treatment in cancer patients is regulated according to the type of disease.
If any of these signs or symptoms have been present for more than two weeks, Need to be treated. They may not be linked to cancer. However, evaluation by a physician is required. The purpose of the petition is; Diagnosis and treatment of the disease a thousand years ago.
