Answer all of these questions about cancer. what is cancer? is cancer only one disease? how does cancer affect the cell cycle and the growth of cells? how is this process similar to or different from how an infectious disease affects cells? how do genes play a role in cancer progression? are there any environmental or pathogenic factors that can cause cancer? how does cancer progress in the body? why is cancer difficult to treat in the later stages? what do the terms stage and grade mean in the context of cancer? what current treatments exist for cancer? what treatments are on the horizon? what are the challenges of treating or curing cancer?

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.

hello there,

guys i’m confused.
