Step-by-step explanation:

Cancer is an umbrella term for a bunch of related diseases. When a cell malfunctions and causes unnecessary growth: that is a cancer. This affects cells by making them too swollen to work probably, and sometimes be eroded and destroyed. The cancer quickly spreads once one infected cell has made it past security, much like a virus. Our genes play a role because if we have dormant or late-blooming cancer, I can pass it on genetically to my offspring without knowing. Sometimes cancer runs in someone's family. Air pollution, nuclear waste, and radioactivity can all cause cancer. Cancer progresses by following the flow of blood cells throughout the body, the later into the stages of cancer the more likely the cancer has reached the heart or spinal cord, in which it would be impossible to fully remove the growth. The grade depends on how mutated the cell has become when observed under a microscope. Later stages usually spread faster than earlier stages of cancer. There is no definite all-serving way to cure cancer. Many times once cancer has appeared once it will come back later. There are some methods to backlash against the spread that sometimes run the cancer completely away. Surgery, chemotherapy, radiotherapy, cancer drugs, hormone therapy, stem cell and bone marrow transplants. A new treatment gives the cancer photosensitivity drugs so that laser light can kill the cells, but this only works on certain cases. One of the challenges to treating and curing cancer is that it's very hard to detect in early stages, usually by the time you see symptoms it's too late. Another challenge is its resistance and stubbornness to treatment. Cancer usually doesn't go away without taking a portion of the person with it, and often ends up returning because the body has become susceptible.

Answer 2

Cancer is the name given to a collection of related diseases. Cancer is more than one type of disease.

In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation.

CAD, Stroke, Respiratory illness, COPD are all diseases related to cancer.

Inherited genetic mutations play a major role in about 5 to 10 percent of all cancers.

There are many environmental pathogenic factors that can cause cancer. For example , Tar and Coal-Tar Pitch , Emissions , Secondhand Tobacco Smoke (Environmental Tobacco Smoke) , Arsenic , Soot , Asbestos , Wood Dust.

When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system. Cancer is hard to treat in later stages because it probably has already spread through out the body.

The grade of a cancer depends on what the cells look like under a microscope. In general, a lower grade indicates a slower-growing cancer and a higher grade indicates a faster-growing one.

Some examples of cancer treatments of cancer are, Surgery, Chemotherapy, Radiotherapy, Cancer drugs, Hormone therapy, Stem cell and bone marrow transplants, Targeted cancer drugs.

A new treatment involving a photosensitising agent that makes cells more sensitive to light and, by doing so, causes cancer cells to be destroyed when a laser light is directed on a cancerous area.

One challenge is, druggable genomic alterations are diverse and represent only small subsets of patients in certain tumor types, which limits testing their clinical impact in biomarker-driven clinical trials. Next-generation sequencing technologies are increasingly being implemented for molecular prescreening in clinical research, but issues regarding clinical interpretation of large genomic data make their wide clinical use difficult.
