What is cancer?
During our entire life, healthy cells are divided into our body and replace themselves in a controlled fashion. Cancer begins when a cell is changed in some way so that it is out of control. A tumor is a mass made up of a group of such abnormal cells.
Most cancers frame tumors, yet not all tumors are dangerous.
Gentle, or non-cancerous, tumors do not spread in other parts of the body and do not make new tumors. Fatal, or cancerous, tumors take out healthy cells, interferes with body functions, and attracts nutrients from body tissues.
Cancer progresses and spreads through a process called straight extension or metastasis, where fatal cells travel through the lymph or blood vessels – eventually new tumors are formed in other parts of the body.
The word “cancer” covers more than 100 diseases affecting almost every part of the body, and all potentially threatens life.
The real kinds of malignant growth are carcinoma, sarcoma, melanoma, lymphoma and leukemia. Carcinoma – The most commonly diagnosed cancer – is produced in the skin, lungs, breast, pancreas and other organs and glands. Lymphoma is the cancer of lymphocytes. Leukemia is cancer of the blood. It usually does not make solid tumors. Cercoma is produced in bones, muscles, fats, blood vessels, cartilage or other soft or connective tissues of the body. They are relatively unusual. Melanoma is a cancer that is produced in cells that make pigment in the skin.
Cancer has been recognized for thousands of years in the form of human disease, yet in the last century only medical science has understood what cancer is really and how it progresses. Cancer experts, who are called oncologist, have made significant progress in cancer diagnosis, prevention and treatment. Today, more people diagnosed with cancer are living for a long time. However, it is frustrating to treat some forms of illness. Modern treatment can improve the quality of life and can increase survival.
How Is Cancer Diagnosed?
The earlier cancers are diagnosed and treated, the chances of recovering are better. Some types of cancers – such as skin, breast, mouth, testicles, prostate, and rectum – can be detected by regular self-test or other screening measures before the symptoms become severe. Most cases of cancer are detected and after diagnosis of a tumor or other symptoms, it is diagnosed. In some cases, cancer is diagnosed as a result of the evaluation or treatment of other medical conditions.
The diagnosis of cancer begins with the complete physical examination and complete medical history. Laboratory studies of blood, urine and feces can detect abnormalities which can indicate cancer. When a tumor is suspected, imaging tests such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and fiber-optic endoscopy tests help doctors determine the location and size of the cancer. Are. To confirm the diagnosis of most cancers, a biopsy is required in which a tissue sample is removed from the suspected tumor and is studied to examine the cancer cells under a microscope.
If the diagnosis is positive (cancer is present), then other tests are done to provide specific information about cancer. This necessary follow-up stage of diagnosis is called staging. The doctors should know the most important thing about whether the cancer has spread from one area of the body to another. If the initial diagnosis is negative for cancer and symptoms persist, further tests may be required. If biopsy is a positive for cancer, then be sure to confirm an opinion by a doctor specializing in the treatment of cancer before the beginning of any treatment.
What are the treatments for cancer?
Depending on the type and condition of cancer, removing tumors or slowing its growth may include some combination of surgery, radiation therapy, chemotherapy, hormone therapy or immunotherapy.
Assistant care should be done with nurses and other professionals with cancer treatment. To eliminate target pain and other symptoms, to maintain normal health, to improve the quality of life and provide emotional, psychological and logical support to patients and their families. Similar healing treatment is available for rehabilitation of patients after remedial treatment. For the therapeutic therapy, such as cancer patients, near the end of their life, the hospice care provides relief from pain and other irreversible symptoms. Most mainstream care is done to provide helpful treatment through extensive resources of a cancer treatment center. Supplemental cancer treatments, which are usually provided outside of a hospital, can also provide support.
