Cancer is a disease caused by abnormal growth of body tissue cells are transformed into cancer cells. During development, these cancer cells can spread to other body parts that can cause death.
Cancer is often known by the public as a tumor, but not all tumors are cancerous. The tumor is any abnormal lumps or abnormal. Tumors were divided into 2 groups, namely benign and malignant tumors. Cancer is a general term for any type of malignant tumor (About Cancer)
Cancer can happen to all people, in every part of the body, and on all gologan age, but more often affects people over the age of 40 years.
Generally, before the cancer spread or damage the surrounding tissue, the patient does not feel any complaints or symptoms. When you have any complaints or symptoms, the disease is advanced.
There are 7 symptoms that need to be considered and further examined by a doctor to ascertain the presence or absence of cancer, namely:
- When large or small bowel habits no change or interruption.
- Disturbed digestion and swallowing difficult.
- Hoarseness or a cough that will not go away
- Breast or anywhere else there is a lump (tumor).
- Moles are changed in character, becoming increasingly large and itchy.
- Abnormal blood or mucus out of the body
- The presence of scabs or ulcers that would not heal.
Most types of cancer can be prevented with healthy habits at a young age and avoid the factors that cause cancer.
Although the exact cause of cancer is not known, everyone can take steps to prevent a healthy lifestyle and avoid the causes of cancer:
1. Regarding food:
- Reduce excessive fatty foods
- Eat more fibrous foods.
- Eat more colorful vegetables and fruits, a few times a day
- Eat more fresh food
- Reduce foods that have been preserved or stored too long
- Limiting alcohol
3. Avoid the habit of smoking. For smokers: quit smoking.
4. Strive life balance and avoid stress
5. Health check periodically and regularly.
Factors that may increase the risk of cancer
Substances contained in cigarette smoke can cause various types of cancer in smokers and passive smokers (non-smokers who do not accidentally inhale other people's smoke) in a long time. Chemicals for industrial and smoke containing carbon compounds can increase the likelihood of an industrial worker suffering from cancer.
Ultra violet rays from the sun can cause skin cancer. Radioactive rays, X-rays or excessive radiation rays can cause skin cancer and leukemia.
Some types of viruses closely related to the transformation of normal cells into cancer cells. This type of virus called a virus that causes cancer or oncogenic viruses.
Hormones are substances produced gland body whose function is to regulate the activities of organs of a particular film. In some studies it is known that certain hormone excess can lead to increased incidence of some cancers such as breast, uterus, ovary and prostate (male sex glands).
Substances or chemicals found in certain foods can cause cancer such as food stored old and moldy can be contaminated by aflatoxin. Aflatoxin is a substance produced fungus Aspergillus flavus that can increase the risk of liver cancer.
Examination and Treatment of Cancer
For those who are suspected, the examination can be done is:
- Cytology and anatomic pathology
- Tests sign of cancer in the blood
- Mammography (x-ray specific to breast)
- Ultrasound / Ultrasound (organ photographing the inside)
- Endoscopy (observation of inner organs)
- Colposcopy (cervical observation)
- Laparoscopic (observation of the abdominal cavity)
- Shooting the layers of the body by means of CT Scan, MRI (Magnetic Resonance Imaging)
Cancer treatment consisted of one or a combination of the following procedures:
- Surgery (surgery)
- Radiation (Radio-therapy)
- Use of drugs cancer cell killing (sitostatika / chemotherapy)
- Increased endurance (immunotherapy)
- Treatment with hormones
- Organ transplantation.
- Stem Cell
The results of treatment depends mainly on the stage or degree of cancer
