Definition And Cause of Cancer

What is the cause of cancer?

The Cause of cancer. Generally, cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. It is caused by changes in DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes. Especially cancer is not one disease. It is a group of more than 100 different and typical diseases. It can involve any tissue of the body and have many different forms in each body area. Cancer is one of the highest causes of death in the world.

What is Cancer Growth and Metastasis

Such as in a healthy body, the trillions of cells it’s made of grow and divide, as the body needs them to function daily. Healthy cells have a specific life cycle, reproducing, and dying off in a way that is distinguished by the type of cell. Accordingly, new cells take the place of old or damaged cells as they die. In this case, it disrupts this process and leads to abnormal growth in cells. In this case, it is caused by changes or modifications in DNA.

Know the Cause of cancer

For example, DNA lives in the respective genes of every cell. Such as it has instructions that tell the cell what acts to perform and how to grow and divide. Modifications occur frequently in DNA, but usually, cells correct these mistakes. When a mistake is not corrected, a cell can become cancerous.

Modifications can cause cells that should be replaced to survive instead of die, and new cells to form when they’re not needed. So then these extra cells can divide uncontrollably, causing growths called tumors to form. For instance, tumors can cause a variety of health problems, depending on where they grow in the body.

Cause of cancer

But not all tumors are cancerous. Therefore benign tumors are noncancerous and do not spread to nearby tissues. Sometimes, they can grow large and cause problems when they press against neighboring organs and tissue. Likewise Malignant tumors are cancerous and can infect other parts of the body.

Cause of cancer

Some cancer cells can also migrate through the bloodstream or lymphatic system to distant areas of the body. In brief, this process is called metastasis. Such cancers that have metastasized are considered more advanced than those that have not. Also, Metastatic cancers tend to be harder to treat and more fatal.

Types of Cancer

Generally, cancers are called for the area in which they begin and the type of cell they are made of, even if they spread to other parts of the body. For example, cancer that begins in the lungs and spreads to the liver is still called lung cancer. There are also several clinical terms used for certain general types of cancer:

  • Carcinoma is cancer that starts in the skin or the tissues that line other organs.
  • Sarcoma is a cancer of connective tissues such as bones, muscles, cartilage, and blood vessels.
  • In brief, Leukemia is a cancer of the bone marrow, which creates blood cells.
  • In particular, Lymphoma and myeloma are cancers of the immune system.

Risk Factors and Treatment

The direct cause of cancer is changes (or modifications) to the DNA in your cells. Genetic mutations can be inherited. They can also occur after birth as a result of environmental forces. Some of these forces include:

  • exposure to cancer-causing chemicals, called carcinogens
  • exposure to radiation
  • unprotected exposure to the sun
  • certain viruses, such as human papilloma virus (HPV)
  • smoking
  • lifestyle choices, such as type of diet and level of physical activity

Accordingly, cancer risk tends to increase with age. Some existing health conditions that cause inflammation may also increase your risk of cancer. An example is an ulcerative colitis, a chronic inflammatory bowel disease.

Cause of cancer

In particular, knowing the factors that contribute to cancer can help you live a lifestyle that decreases your cancer risks. According to specialists, these are the seven best ways to prevent cancer:

  • Stop using tobacco and avoid secondhand smoke.
  • Eat a healthy, balanced diet.
  • Keep a healthy weight and stay active by getting at least 30 minutes of physical activity every day.
  • Stay protected from the sun.
  • Get a vaccine against viral infections that can lead to cancer, such as hepatitis B and HPV.
  • Don’t engage in risky behaviors. Practice safe sex and don’t share needles when using drugs or prescription medications. Only get tattoos at licensed parlors.
  • See your doctor regularly so they can screen you for various types of cancer. This increases your chances of catching any possible cancers as early as possible.

Cause of cancer

Generally, cancer treatment has different objectives, it depends on the type of cancer and how to advance it is. These objectives include:

  • Finding a cure: This is not likely for all cancers and situations.
  • Providing primary treatment: Killing the cancer cells in your body.
  • Getting adjuvant treatment: Killing cancer cells that remain after primary treatment to reduce your risk of cancer coming back.
  • Providing analgesia treatment: Relieving health symptoms associated with cancer, such as trouble breathing and pain.

The most common types of treatment are:

Surgery

Surgically removes as much of the cancer as possible.

Chemotherapy

Uses medications that are toxic to cells to kill rapidly-dividing cancer cells.

Radiation Therapy

Uses powerful, focused beams of radiation inside (brachytherapy) or outside (external beam radiation) your body to kill cancer cells.

Stem Cell (Bone Marrow) Transplant

Repairs diseased bone marrow with healthy stem cells. Stem cells undifferentiates cells that can have a variety of functions. These transplants allow medics to use higher doses of chemotherapy to treat cancer.

Immunotherapy (Biological Therapy)

Uses antibodies to help your body’s immune system recognize cancer so it can fight it off.

Hormone Therapy

Removes or blocks hormones that fuel certain cancers to stop cancer cells from growing.

Targeted Drug Therapy

Uses drugs to interfere with certain molecules that help cancer cells grow and survive.

Clinical Trials

Investigates new ways to treat cancer.

Alternative Medicine

Used to decrease symptoms of cancer and side effects of cancer treatment, such as nausea, fatigue, and pain. Alternative medicine includes:

  • acupuncture
  • hypnosis
  • massage
  • yoga
  • meditation
  • relaxation techniques
