Cancer Causes, Symptoms and Treatment of Cancer

cancer information

Cancer is when abnormal cells divide in an uncontrolled way. Some cancers may eventually spread into other tissues. There are more than 200 different types of cancer.

Cancer starts when gene changes make one cell or a few cells begin to grow and multiply too much. This may cause a growth called a tumour. A primary tumour is the name for where a cancer starts. Cancer can sometimes spread to other parts of the body – this is called a secondary tumour or a metastasis. Cancer and its treatments can affect body systems, such as the blood circulation, lymphatic and immune systems, and the hormone system.

Most cancers start due to gene changes that happen over a person’s lifetime.More rarely cancers start due to inherited faulty genes passed down in families.

Cancers are divided into groups according to the type of cell they start from. They include

  • Carcinomas
  • Lymphomas
  • Leukaemias
  • Brain tumours
  • Sarcomas

Cancer occurs when cells become abnormal and keep dividing and forming more cells without control or order, forming a growth or tumor. Benign tumors are NOT cancer; malignant tumors are cancer. Cancer stem cell content and the intrinsic radio sensitivity of cancer stem cells is thought to vary between tumors, thereby affecting their radio curability. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis.

Causes, Symptoms and Treatment of Cancer

Symptoms and treatment depend on the cancer type and how advanced it is. Treatment plans may include surgery, radiation and/or chemotherapy. Causes of Cancer cells are the building blocks of living things. Cancer grows out of normal cells in the body. Normal cells multiply when the body needs them, and die when the body doesn’t. Cancer appears to occur when the growth of cells in the body is out of control and cells divide too rapidly. It can also occur when cells “forget” how to die. There are many different kinds of cancers. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue. The mutation in the DNA changes these instructions, so that the cells carry on growing. This causes the cells to reproduce in an uncontrollable manner producing a lump of tissue, known as a tumors.

Symptoms of cancer depend on the type and location of the tumor. For example, lung cancer can cause coughing, shortness of breath, or chest pain, while colon cancer often causes diarrhea, constipation, and blood in the stool. Local symptoms – these occur when the cancer is contained in one part of your body. changes in bowel or bladder habits, a sore that does not heal, unusual bleeding or discharge, thickening or lump in the breast or any other part of the body, indigestion or difficulty swallowing, obvious change in a wart or mole, or nagging cough or hoarseness.

Types of Cancer

Some major types of cancer are breast cancer, prostate cancer, lung cancer, cancer of colon or rectum, bladder cancer and ovarian cancer.

Treatment of Cancer

Treatment also varies based on the type of cancer and its stage. The stage of a cancer refers to how much it has grown and whether the tumor has spread from its original location If the cancer is confined to one location and has not spread, the goal for treatment would be surgery and cure. If the tumor has spread to local lymph nodes only, sometimes these can also be removed.

Some of Cancer treatment methods are


The method is used in localized cancer. This is cancer that is contained in one area. Here the doctors take you to the theater and surgically remove the cancellous material. The surgery can be open or invasive. In open surgery, the surgeon makes a large cut and removes healthy tissues, the tumor, and sometimes the nearby lymph nodes. In invasive surgery, the surgeon makes a few small cuts and inserts a long, thin tube with a camera into the small cuts. The camera helps the doctor to monitor the inside of the body so that he/she can see what he/she is doing.


The method uses drugs to kill cancer cells. The treatment method works by stopping or slowing down the growth of cancerous cells.

chemotherapy process

Doctors use the method to treat cancer and also ease the disease symptoms. Depending on the extent of your cancer, the treatment can be used alone or to help other methods. While the method is useful, its principal flaw is that the medications used tend not only to kill the tumor cells, it also kills the healthy cells.

Hormone therapy

Hormone therapy is used in the treatment of cancer that uses hormones to grow. The treatment works in two ways. It can block the body’s ability to produce hormones. It can also interfere with how hormones behave in the body. In most cases, it’s used with other treatment options where it reduces the size of the cancer cells. It also lowers the risk of cancer coming back and kills the cancer cells that might have returned or spread to other parts of the body.

Targeted therapy

Targeted therapy is the foundation of precision medicine. The treatment method focuses the parts that help the cancer cells to grow, spread, and divide. The method works in many ways. It helps the immune system to destroy cancer cells, stops the cancer cells from growing, prevents the signals that help the formation of blood vessels and causes the cancer cells to die.

Radiation therapy

This treatment option relies on high doses of radiation to kill cancer cells and shrink tumors. At high doses, radiation kills cancellous cells or slows their growth by damaging their DNA. The treatment option doesn’t kill the cells right away-it takes a few days or weeks to do so.

  1. Paul M says:

    By easy, I mean a disease that’s easy to understand. One that has all answers to. Treatments, symptoms, occurrence, cause, history, everything. Can anyone help me with this?

    I think that the better I understand the disease, the better I can explain it.
