The Cause, Symptoms, and Treatment of Nodular Melanoma Tatyana Bichkova Kingborough Community College The largest of all the organ's in the body is the skin. Skin is also on the exterior part of the body and it protects us from sunlight, infection, injury, and heat. Many people that do not protect their skin from the sun and can develop one of the three different types of cancers. These are basal cell skin cancer, squamous cell skin cancer, or melanoma. Melanoma is more severe then squamous cell or basal cell skin cancer.
Chapter 5 Section 3: Regulation of the Cell Cycle Main Ideas: Internal and external factors regulate cell division Cell division is uncontrollable in cancer Questions: 1. Describe what a growth factor is and how it influences the cell cycle. A growth factor is a broad group of proteins that stimulate cell division, this influences the cell cycle because it is what ‘stimulates the cell division’, which is a main factor in the cell cycle. 2. Explain how cancer cells differ from healthy cells.
Mutations happen often, and the human body is normally able to correct most of these changes. Depending on where in the gene the change occurs, a mutation may be beneficial, harmful, or make no difference at all. Therefore, the likelihood of one mutation leading to cancer is small. Usually, it takes multiple mutations over a lifetime to cause cancer, This is why cancer occurs more often in older people, for whom there have been more opportunities for mutations to build up (Cancer.Net). The most dangerous form of skin cancer is Melanoma.

Skin cells are always being overwhelmed with radiation and certain genes are responsible for fixing the damage. When a gene called Patch is inactivated it causes an increase in excessive cell growth, also known as cancer. Patch was found in a fruit fly called Drosophila melanogaster. Patch is located on the ninth chromosome in humans. Malfunctioning patch leads to defective embryonic development and many types of skin cancer.
The ACS goes on to say that, Cancers of the pancreas, for example, usually doesn’t cause symptoms until they grow large enough to press on nearby nerves or organs (this causes back or belly pain). Others may grow around the bile duct and block the flow of bile. This causes the eyes and skin to look yellow (jaundice). By the time a pancreatic cancer causes signs or symptoms like these, it’s usually in an advanced stage. This means it has grown and spread beyond the place it started – the pancreas
The chromosomes condense and become visible Metaphase II- the chromosomes align down the center of the cell Anaphase II- the centromeres part and the separated sister chromatids move to opposite poles Telophase II- nuclear envelopes form, and cytokinesis then separates the nuclei into individual cell Crossing over- is a process in which two homologous chromosomes exchange genetic material Polyploid- an error in meiosis, gamete with one or more complete cells of extra chromosomes Nondisjunction- abnormality error, occurs when the chromosomes fail to separate at either the first or second meiotic
To treat all the diseases with ES cells doctors takes cells and develops them into neurons. For treating the diseases with adult stem cells doctors gets cells from either the fetal or adult central nervous system (CNS). Adult stem cell and embryonic stem cells can treat brain, Chronic Myelogenous Leukemia, breast cancers and many more. (Lindvall and Kokaia). For treating Parkinson's disease with adult stem cells have to replace the cells that have died with other identical dopaminergic neurons (Euro Stem Cell).
However, if the cell is able to recover, it may begin to proliferate widely in the uncontrolled growth of cancer. Don’t let these facts scare you into living in a bubble. Every day we engage in fatal games of chance that can ultimately lead to some form of human malady. Only about 1% of fatal human cancers are caused by the 30 trillion particles of radiation that we encounter throughout our
The first test is a lab test or blood work that can be monitored and checked with routinely, it is called a PSA test or prostate specific antigen. This test is not always accurate and can even be elevated when there is no cancer present; this is known as a false positive. It has been said by those with prostate cancer that they believe through experiences of their own, that it is most important in how fast the PSA numbers climb as to the increased risk of having a rapid growing cancer. PSA is mostly found in semen, but a small amount is found in the blood as well. The standard is when it rises above 4ng/ml, if not done earlier; a deeper diagnostics should be initiated at this time.
