What is Cancer?

Cancer develops when cells in a part of the body begin to grow out of control. Although there are many kinds of cancer, they all start because of uncontrolled growth of abnormal cells.

Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide more rapidly until the person becomes an adult.

After that, cells in the most parts of the body divide only to replace worn-out or dying cells and repair injuries.

As cancer cells continue to grow and divide, they are different from normal cells. Instead of dying, they outlive normal cells and continue to form new abnormal cells.

Cancer cells often travel to other parts of the body where they begin to grow and replace normal tissue.

The process, called metastasis occurs as the cancer cells get into the bloodstream or lymph vessels of our body.

When cells from breast cancer spread to another organ like the liver, the cancer is still called breast cancer, not liver cancer.

Cancer cells develop because of damage to DNA. Most of the time when DNA becomes damaged the body is able to repair it.

In cancer cells, the damaged DNA is not repaired. People can inherit damaged DNA, which accounts for inherited cancers.

Many times though, a person’s DNA becomes damaged by exposure to something in the environment, like smoking.

Cancers usually forms as tumor. Some cancers, like leukemia, do not form tumors. Instead, these cancer cells involve the blood and blood-forming organs and circulate through other tissues where they grow.

Remember that not all tumors are cancerous. Benign (non-cancerous) tumors do not spread to other parts of the body (metastasize) and, exceptionally, are not life threatening.

Different types of cancer can behave very differently. For example, lung cancer and breast cancer are very different diseases. They grow at different rates and respond to different treatments.

SYMPTOMS of CANCER

Signs and early detection:- A symptoms is an indication of disease, illness, injury, or that something is not right in the body.

Symptoms are felts or noticed by a person, but may not easily be notice by anyone else. For example, chills, weakness, pain in the body part, breathlessness, and cough are possible symptoms of pneumonia.

Just a symptoms is also an indication that something is not right the body. But symptoms are define as observations made by a doctor, nurse, or other health care professionals.

Fever, rapid breathing rate, and abnormal breathing sounds heard through a stethoscope are possible symptoms of pneumonia.

Cancer is a group of diseases, that may cause any sign or symptoms. The signs and symptoms will depend on the stage and type of the cancer.

If a cancer spreads (metastasizes), then symptoms may appear in different parts of the body.

As a cancer grows, it begins to push on nearby organs, blood vessels and nerves. This pressure creates some of the signs ans symptoms of cancer.

If the cancer is in a critical area, such as certain parts of the brain, even the smallest tumor can produce early symptoms.

A cancer may also cause generalized symptoms such as fever, fatigue, or weight loss. This may caused be cancer cells releasing substances that change the body’s metabolism.

The cancer may cause the immune system to react in ways that produce these symptoms.

Sometimes, cancers cells release substances into the bloodstream that cause symptoms not generally thought to result from cancers.

For example, some cancers of the pancreas can release substances, which cause blood clots to develops in veins of the legs.

Some lungs cancers produce hormone-like substance that affect blood calcium levels, affecting nerves and muscles and causing weakness and dizziness.

Side effects of cancer in human beings

Cancer and cancer treatment often cause a variety of side effects. Talk with your doctor about which side effects are likely based on your specific treatment plan. An important part of cancer care is relieving side effects, called symptom management, palliative care, or supportive care. It is important to talk with your health care team about the specific side effects you experience and the best ways to manage and treat them.
