syöpävaurio

Syöpävaurio, also known as a tumor or neoplasm, refers to an abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should. This uncontrolled cell proliferation can occur in any part of the body.

Tumors can be broadly classified into two categories: benign and malignant. Benign tumors are non-cancerous. They typically grow slowly, do not invade surrounding tissues, and do not spread to other parts of the body. While they can cause problems by pressing on nearby organs or tissues, they are generally not life-threatening.

Malignant tumors, on the other hand, are cancerous. They have the ability to invade surrounding tissues and can spread to distant parts of the body through the bloodstream or lymphatic system, a process called metastasis. This ability to invade and metastasize is the hallmark of cancer.

The causes of syöpävaurio are complex and can involve genetic mutations, environmental factors such as exposure to carcinogens, lifestyle choices like smoking and poor diet, and infectious agents. The specific characteristics of a syöpävaurio, including its size, location, and whether it is benign or malignant, determine the symptoms it may cause and the appropriate treatment options. Diagnosis often involves imaging techniques, biopsies, and laboratory tests.
