Cancer is caused by abnormal cells that divide rapidly, uncontrollably, and spread throughout the body. It often has no symptoms in the early stages. Prevention, screening, and regular health care should be carried out.
Cancer is a disease caused by abnormal cells in the body and these cells grow faster than normal. The body cannot control them. These cells then spread and spread throughout the body. As a result, normal cells of various tissues/organs fail and cannot function normally. This eventually causes death, including lungs, liver, brain, kidneys, bones and bone marrow. The symbol of cancer is the crab. The word cancer comes from the Greek word Carcinos, which means crab.
Because the cancerous tumor has the characteristic of spreading out from the tumor itself like a crab’s legs spreading out from the body of a crab, the first person to use this term was Hippocrates, the father of Western medicine.
Cancer process
When the body is exposed to carcinogens such as chemicals, viruses, and radiation, these things cause cells to change and eventually normal cells will become cancer cells. โปรโมชั่นพิเศษจาก UFABET สมัครตอนนี้ รับโบนัสทันที. If the body’s immune system cannot destroy the cells, the cancer cells will divide rapidly and become cancerous tumors.
Cancer VS Tumor
Cancer is different from tumors in that tumors or cancerous lesions grow quickly and spread to nearby organs, lymph nodes, and blood vessels, bloodstream, and lymphatic vessels or lymphatic flow to tissues or organs throughout the body, often spreading to the lungs, liver, brain, bones, and bone marrow. Therefore, cancer is a chronic, severe disease with complex and continuous treatment. On the other hand, tumors are truly abnormal lumps, but grow slowly, do not spread to nearby tissues or organs, and do not spread through the bloodstream and lymphatic flow. Therefore, it is a disease that can be cured by surgery.
Causes of cancer
The exact cause of cancer is currently unknown, but it is believed that there are several factors involved in its development.
Causes from external environmental factors
- Certain chemicals, such as those found in cigarette smoke and vehicle soot, toxins from mold, toxins from smoked, grilled, roasted, or charred meats, fabric dyes, certain chemicals from industrial processes, and various types of radiation, including ultraviolet radiation in sunlight.
Chronic infection
- Hepatitis B virus is associated with the development of liver cancer.
- Human papilloma Virus (HPV) may be associated with the development of cancers of the cells of the lining of the body, such as cervical cancer.
- Epstein Barr virus is associated with the development of lymphoma or nasopharyngeal cancer.
- Helicobacter Pylori is associated with stomach cancer.
- Parasites such as liver fluke are associated with intrahepatic bile duct cancer.
Internal causes
- Genetic abnormalities
- Hormonal imbalance
- Deficient immune system
- Recurrent irritation over a long period of time
- Malnutrition, etc.
Symptoms suspected of cancer
There are no specific symptoms of cancer, but they are similar to inflammation of cancerous tissue or organs, with the difference being that they tend to get worse and are chronic. Therefore, if you have any of these symptoms for more than 1-2 weeks, you should see a doctor immediately. However, symptoms that suggest cancer include:
- There is a rapidly growing lump or a chronic wound that does not heal within 1-2 weeks after initial self-care.
- There are swollen lymph nodes that can be felt, are usually firm, painless, and continue to grow larger.
- Moles, birthmarks, warts that grow abnormally fast or become sores
- Bad breath or bad breath that you never had before
- Chronic nosebleeds, usually occurring on one side only (may occur on both sides)
- Chronic cough or coughing up blood
- Frequent phlegm, saliva, or sputum mixed with blood
Cancer symptoms
- Vomiting blood
- Blood in urine
- Frequent urination, obstruction, and urine leakage that you have never experienced before
- Bloody, mucusy, or bloody stools
- Constipation alternating with diarrhea, never before experienced
- Abnormal vaginal bleeding or menstrual bleeding, or vaginal bleeding during menopause or after sexual intercourse when you have never had it before.
- Bloating, flatulence, tightness, and stomach discomfort that you have never experienced before
- Low-grade fever of unknown cause
- Frequent high fever, unexplained cause
- Lost a lot of weight in 6 months, lost 10% of my original weight.
- Frequent bruising or red spots similar to dengue fever on the skin
- Severe, chronic headache, or weakness in the arms/legs, or seizures without previous seizures
- Chronic and progressive back pain, possibly accompanied by arm/leg weakness
Cancer screening
Is the detection of cancer before it shows any symptoms (usually stage 0 or stage 1 cancer). This is because cancer at this stage has a higher chance of being cured than cancer at other stages. Effective cancer screening is when the disease is detected. After treatment, patients will have a higher survival rate from cancer or a lower death rate from cancer. Currently, effective cancer screening includes screening for cervical cancer, breast cancer, and colon cancer .
Prevent cancer
- Eat nutritious food from all 5 food groups every day in appropriate amounts, meaning not too fat or too thin. Limit red meat, flour, sugar, fat, and salt, but increase vegetables and fruits.
- Exercise regularly to maintain good health.
- Get a cancer screening/annual health checkup
- Avoid carcinogens
