Cancer is a parasol term for a broad group of illnesses produced when irregular cells divide quickly and spread to other tissues and organs. Cancer is one of the preeminent causes of death in the world.
We tried to compile everything about cancer. Read the complete article to know everything about cancer!
Cancer Growth & Metastasis
We all know that trillions of cells are made of growing & dividing so that the body can function every day properly. However, healthy cells have a definite life cycle. The new cells replace the old cells. And cancer intrudes into this process and begins irregular growth in cells caused by changes or mutations in DNA.
DNA lives in the single genes of every cell. It has directions that explain to the cell what functions to accomplish and how to develop and distribute. However, mutations happen regularly in DNA, but usually, cells fix these errors. When an error is not fixed, a cell can convert into cancerous.
Types of cancer
Despite spreading to other parts of the body, cancers are named for the site where they originate and the type of cell they are made of. Lung cancer, for example, can still be called lung cancer despite growing in the liver. However, there are also clinical terms-
- Carcinoma is a cancer of the skin or tissue lining other organs.
- Sarcoma is a cancer of connective tissues for example bones, muscles, blood vessels, and cartilage.
- Leukemia is a cancer of the bone marrow.
- Lymphoma & myeloma are cancers of the immune system.
The primary reason for cancer is changes (or mutations) to the DNA in your cells. Hereditary mutations can be acquired. They can also happen after birth as a consequence of environmental forces. Some of these forces are-
- viruses i.e. human papillomavirus (HPV)
- lifestyle choices
- vulnerability to radiation
- unprotected vulnerability to the sun
- vulnerability to cancer-causing chemicals known as carcinogens
By understanding how cancer arises, you can lead a lifestyle that reduces your cancer risks. Some of the best ways are-
- Quit using tobacco and withdraw secondhand smoke.
- Eat a balanced & healthy diet.
- Maintain a healthy weight and stay active by exercising at least 30 minutes a day.
- Stay shielded from the sun.
- Get vaccinated against cancer-causing viruses like hepatitis B and HPV.
- Don’t involve yourself in dangerous habits. Follow secure sex and don’t share needles when using drugs or prescription medications. Only get tattoos in authorized parlors.
- Consult your doctor periodically so they can screen you for several types of cancer. This improves your odds of detecting any possible cancers as early as possible.
Cancer treatment has several purposes, depending on the type of cancer and how difficult it is. These purposes are:
- Finding a remedy
- Giving primary treatment
- Giving adjuvant treatment
- Giving palliative treatment
The most popular types of treatments are-
It eliminates as much cancer as possible.
It is used to kill rapidly dividing cancer cells by using medications that are toxic to cells.
To kill cancer cells, a powerful, focused beam of radiation is used inside (brachytherapy) or outside (external beam radiation).
Stem Cell (Bone Marrow) Transplant
Rebuilds damaged bone marrow with healthy stem cells. Stem cells are similar cells that can have a variety of purposes. These transplants permit doctors to apply higher dosages of chemotherapy to tackle cancer.
Immunotherapy (Biological Therapy)
Utilizes antibodies to help your body’s immune system identify cancer so it can battle it off.
Transfers or kills hormones that feed several cancers to stop cancer cells from growing.
Targeted Drug Therapy
Interferes with certain molecules that help cancer cells grow and survive.
Studies new ways to treat cancer.
Applied to reduce signs of cancer and side effects of cancer therapy, like nausea, fatigue, and pain. Complementary medicine involves:
- relaxation techniques
