What is cancer?

Cancer is a disease caused by an uncontrolled growth of cells, which we call a tumor, that can start anywhere in the body. This uncontrolled growth causes problems in the place where it occurs, and cancer cells can also migrate to other places in the body, causing what is known as metastasis

There are more than 200 different types of cancer that can be more or less aggressive and have different chances of metastasizing. In recent years, the incidence of cancer has increased due in part to the longer lifespan of the population, as well as increased exposure to carcinogenic factors. Carcinogenic factors are substances that promote the development of cancer. 

Cancer is a genetic disease. This means that it is caused by changes in the genes that control the functioning of our cells, especially in terms of how they grow and divide. Genetic changes that cause cancer can be inherited from parents, but inherited cancers are rare. In most cases, the genetic changes can arise during a person’s lifetime as a result of damage to their DNA by certain agents such as tobacco smoke, radiation and ultraviolet rays from the sun. 

The signs and symptoms of cancer depend on the type of cancer and its location. Certain symptoms common to most tumors include: fatigue, loss of appetite and subsequent weight loss. 

The cancer diagnosis is most often made with a biopsy, which involves taking a sample of the growing cells. This sample is studied under a microscope by a pathologist who makes the diagnosis. In addition, the study of the cancer should be accompanied by radiological tests to assess its extent and molecular studies of the biopsy. 

The classification and extent of the cancer are assessed with biopsy and radiological tests. With this information, the cancer is classified into stages (usually I to IV, with IV being the most advanced), which helps predict prognosis and the likelihood of cure. 

Cancer treatment includes local treatments such as surgery or radiotherapy and systemic treatments (those administered into the bloodstream) such as chemotherapy, targeted/biological therapies and immunotherapy. The type of treatment used will depend on the type of cancer and the stage it is in. 

We unite people and science because sharing is moving forward.

  1. Recently, my aunt’s been dealt a tough hand in the health department, and it hit like a ton of bricks. Seeing her battle through the medical maze has been emotionally draining. Amid the struggle, I’ve been digging into cancer support treatments that might bring her some relief, a glimmer of hope in the sea of uncertainty. We’re really grateful you told us that since cancer is a hereditary illness, alterations in the genes that regulate how our cells behave, particularly in terms of growth and division, are the cause of the disease. https://www.innovativemedicalassociates.com/cancer-support-therapy/

  2. It is disheartening to learn that cancer arises from unchecked cell growth, known as a tumor, which can originate from any part of the body. This brings to mind my buddy who has been dealing with health issues lately; it’s as though she’s competing against a heavyweight champion and cancer has made an appearance in the ring. I’ve been urging her that it’s time to go past the one-size-fits-all strategy and pursue the top cancer treatment facility available.

    1. Thank you for your comment!
