How dangerous is cancer?


How dangerous is cancer?Cancer is a special disease: it is cells of one’s own body that get out of control and grow unhindered. A growing Tumor destroys healthy tissue and can form settlements in other areas of the body. Theoretically, the disease can hit anyone. Although there are known risk factors that increase the risk of cancer, but chance plays an important role. Therefore, no one can predict who gets cancer and who doesn’t. Cancer is not from today to tomorrow In cancer development, the genetic material plays an important role 

It Usually takes years or even decades of healthy cells aggressive tumor cells. For cancer to develop, several control mechanisms must fail, which usually prevent unabated growth. Cancer cells are beyond the control of the body in different ways: they grow and share, if you should it actually. They don’t die if they usually die. And they can leave their ancestral place in the tissue and grow in other places in the body. How does such changes occur in the cells? The genetic material plays an important role: if it changes due to external or internal influences or if it is read incorrectly, then the behavior of the cells can also change. There are a number of ways in which cancer cells can acquire the skills that make them so dangerous. Therefore, no Tumor resembles the other. This makes it more difficult to fight cancer or prevent it.

Cancer is a term for a variety of diseases characterized by unbridled cell proliferation and malignant tissue formation and spread in the organism. Surrounding cells are displaced, healthy tissues and organs are restricted in their function. Through blood and lymphatic pathways, the degenerate cells can also spread into more remote regions of the body and there Form daughter ulcers, so-called metastases. According to the World Health Organization, around 14 million new cancer cases occurred worldwide in 2014. Since many of the more than 230 known types of tumors in their formation can not be avoided, early detection plays an important role.

Early detection of Cancer can save lives

Early detection of Cancer can save livesEarly detection programs help to detect tumors in a timely manner and include medical examinations or Tests on persons who have (yet) no complaints. The aim of these studies is to make any changes that indicate cancer visible as early as possible. If the Tumor is still small and locally limited, the chances of healing are usually great.

Observe warning signals

In addition to regular examinations, it is important to pay attention to the body and pay attention to its signals. Unusual changes, swelling, or knots show in the skin, mucosa, or soft tissues, enlarged lymph nodes, as well as poorly healing wounds, you experience symptoms such as blood in the stool or urine, persistent cough or hoarseness, vomiting, pressure, bloating, and unexplained weight loss, then this could be signs of cancer.   The insidious part of many cancers – such as abdomen cancer-is that they often cause no or only unspecific complaints. As a result, they are discovered very late.

The evil word Cancer

Even worse than the primary cancer diagnosis is in most cases the “evil word” recurrent. This term refers to the recurrence of a disease after a symptomless Phase. Simply put, the relapse is a relapse that is far more threatening for many cancer patients than the initial diagnosis. Why a Patient is apparently healed, but after years or even decades the cancer returns, depends on various factors. Also, whether the disease is curable during recurrence, whether one only has to expect a chronic course or whether it becomes life-threatening.  The recurrence of cancer can take place in two different ways. In a local recurrence, a new Tumor grows in the original location and is limited to this location. However, if settlements of the first tumor occur in other places in the body, it is referred to as distant metastases. The risk of recurrence varies by tumor type and stage in primary diagnosis. While some cancers are considered to be cured after five symptomless years, this is not the case with other tumour diseases, such as breast cancer. Studies show that cancer can come back at any time, even after 10 or 25 years.

When the cancer cells migrate

When the cancer cells migrateIf you thought earlier, a cancer grows before you, at some point begins to settle cancer cells and can be healed, if you discover it in time and treat it, so today you know, that this is not always true. Cancers are much more complex. A Tumor can scatter very early, spread small cell clusters or single cells in the tissue or bone marrow. How and why some cancer cells from the primary tumor in other tissue, to settle there and multiply, is currently still an unsolved mystery. For most cancer-related deaths are not the primary tumors, but the metastases responsible.

Sleeping Cells

Not every tumor cell that enters foreign tissue develops into a metastasis. Small islands of cancer cells, which remain in the body after cancer therapy, can be controlled by the immune system, often rest unnoticed for years, before in some cases grow up like out of nowhere to a daughter tumor. The cancer, which appears to be returning, was in reality never gone. Individual cells or small cell clusters are not always easily detectable. However, by means of special procedures such as puncture of the bone marrow, tissue samples or using suitable antibodies and dyes, it is possible to detect and make visible the sleeping tumor cells. An increased concentration of tumour markers can also provide an indication of a renewed cancer.

Chances of a cure

A recurrence of cancer does not automatically mean a life threatening, incurable Situation. How good the chances are depends on many factors, such as the nature of the tumor, the timing and extent of the recurrence. A better prognosis is usually given to patients in which the relapse occurs only later (from two years after the initial diagnosis) and only as a single tumor source. If the relapse occurs again relatively quickly after the first therapy and numerous metastases have formed, the treatment is much more difficult.

Living with cancer

Researchers are constantly working on new strategies to combat or keep tumor cells at bay. The aim of these efforts is to develop drugs for all types of tumors, which allow even those affected at an advanced stage to live permanently without further progression of the disease. Currently, many medicines are in different stages of development – sometimes with promising prospects.
