What is Cancer ?
Cancer refers to abnormal growth of cell tissue. Tumors are usually divided into benign and malignant. A benign tumor is localized, gradually develops and usually does not die of the patient. Malignant or cancerous tumors develop more rapidly. They are not localized and are often fatal to the patient.Some types of cancer run in certain families, but most cancers are not clearly linked to the genes we inherit from our parents
The symptoms and signs of cancer depend on the specific type and grade of cancer; Although the general signs and symptoms are not very specific, the following symptoms can be found in various cancer patients: fatigue, weight loss, pain, skin changes, changes in bowel or bladder function, abnormal bleeding, persistent coughing or voiding. Transformation, fever, lump, or tissue mass.
How does cancer start?
It is a multi-step process in which the cells harm the genetic material and convert the cell to fatal. The damage gradually accumulates in the cellular development regulatory system. A single genetic defect will usually not be enough to cause cancer.
