A description of a diagnosis and possible treatment for cancer

In the absence of coagulative tumor cell necrosis and significant atypia, a high mitotic index is compatible with a benign clinical course. Unlike smooth muscle tumors at other sites, uterine smooth muscle tumors are generally not graded. The distinction is important since grading ULMS based on criteria at other body sites is misleading.

Sources of ionizing radiation include medical imaging and radon gas. Ionizing radiation is not a particularly strong mutagen. Children and adolescents are twice as likely to develop radiation-induced leukemia as adults; radiation exposure before birth has ten times the effect.

Ionizing radiation may be used to treat other cancers, but this may, in some cases, induce a second form of cancer. Cancer syndrome The vast majority of cancers are non-hereditary sporadic.

Hereditary cancers are primarily caused by an inherited genetic defect. Statistically for cancers causing most mortality, the relative risk of developing colorectal cancer when a first-degree relative parent, sibling or child has been diagnosed with it is about 2.

Since height is genetically determined to a large extent, taller people have a heritable increase of cancer risk. It is possible that repeated burns on the same part of the body, such as those produced by kanger and kairo heaters charcoal hand warmersmay produce skin cancer, especially if carcinogenic chemicals are also present.

Chronic inflammation has been hypothesized to directly cause mutation. These higher hormone levels may explain their higher risk of breast cancer, even in the absence of a breast-cancer gene. People with untreated celiac disease have a higher risk, but this risk decreases with time after diagnosis and strict treatment, probably due to the adoption of a gluten-free dietwhich seems to have a protective role against development of malignancy in people with celiac disease.

However, the delay in diagnosis and initiation of a gluten-free diet seems to increase the risk of malignancies. Also, immunomodulators and biologic agents used to treat these diseases may promote developing extra-intestinal malignancies.

Carcinogenesis Cancers are caused by a series of mutations. Each mutation alters the behavior of the cell somewhat. Oncogenomics Cancer is fundamentally a disease of tissue growth regulation.

In order for a normal cell to transform into a cancer cell, the genes that regulate cell growth and differentiation must be altered.

Oncogenes are genes that promote cell growth and reproduction. Tumor suppressor genes are genes that inhibit cell division and survival. Malignant transformation can occur through the formation of novel oncogenes, the inappropriate over-expression of normal oncogenes, or by the under-expression or disabling of tumor suppressor genes.

Typically, changes in multiple genes are required to transform a normal cell into a cancer cell. The gain or loss of an entire chromosome can occur through errors in mitosis. More common are mutationswhich are changes in the nucleotide sequence of genomic DNA.

Large-scale mutations involve the deletion or gain of a portion of a chromosome. Genomic amplification occurs when a cell gains copies often 20 or more of a small chromosomal locus, usually containing one or more oncogenes and adjacent genetic material.

Translocation occurs when two separate chromosomal regions become abnormally fused, often at a characteristic location.

A well-known example of this is the Philadelphia chromosomeor translocation of chromosomes 9 and 22, which occurs in chronic myelogenous leukemia and results in production of the BCR - abl fusion proteinan oncogenic tyrosine kinase.

Disruption of a single gene may also result from integration of genomic material from a DNA virus or retrovirusleading to the expression of viral oncogenes in the affected cell and its descendants.

Replication of the data contained within the DNA of living cells will probabilistically result in some errors mutations. Complex error correction and prevention is built into the process and safeguards the cell against cancer.


If a significant error occurs, the damaged cell can self-destruct through programmed cell death, termed apoptosis. If the error control processes fail, then the mutations will survive and be passed along to daughter cells. Some environments make errors more likely to arise and propagate.

Such environments can include the presence of disruptive substances called carcinogensrepeated physical injury, heat, ionising radiation or hypoxia. A mutation in the error-correcting machinery of a cell might cause that cell and its children to accumulate errors more rapidly. A further mutation in an oncogene might cause the cell to reproduce more rapidly and more frequently than its normal counterparts.

A further mutation may cause loss of a tumor suppressor gene, disrupting the apoptosis signaling pathway and immortalizing the cell.

If you have received a positive or possible diagnosis of breast cancer, there are a number of questions that you can ask your doctor. is designed to provide a framework to help you and your family make certain . Nonalcoholic fatty liver disease or NASH, a disease due to an abnormal accumulation of fat within the liver. Eventually, NASH scars the liver, and it ultimately leads to cirrhosis or liver cancer. Usually, NASH causes no symptoms, but later in the progression of the disease, they may cause jaundice, blood clots, and coma. Treatment for fatty liver include diet, exercise, medication, and surgery. Untreated pancreatic cancer spreads to nearby organs and blood vessels. Most pancreatic cancer begins in the cells that line the ducts of the pancreas. This type of cancer is called pancreatic adenocarcinoma or pancreatic exocrine cancer. Rarely, cancer can form in the hormone-producing cells or the neuroendocrine cells of the pancreas.

A further mutation in the signaling machinery of the cell might send error-causing signals to nearby cells. The transformation of a normal cell into cancer is akin to a chain reaction caused by initial errors, which compound into more severe errors, each progressively allowing the cell to escape more controls that limit normal tissue growth.

Once cancer has begun to develop, this ongoing process, termed clonal evolutiondrives progression towards more invasive stages. Characteristic abilities developed by cancers are divided into categories, specifically evasion of apoptosis, self-sufficiency in growth signals, insensitivity to anti-growth signals, sustained angiogenesis, limitless replicative potential, metastasis, reprogramming of energy metabolism and evasion of immune destruction.

Cancer epigenetics The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis The classical view of cancer is a set of diseases that are driven by progressive genetic abnormalities that include mutations in tumor-suppressor genes and oncogenes and chromosomal abnormalities.Description * Lung cancer is a tumor(s) consisting of lung cells that have ‘mistakes’ in their DNA or genetic coding and reproduce at an abnormal rate.

Lung cancer is one of the most deadly forms of cancer and if left unchecked will spread quickly throughout the body causing illness and death. Prostate cancer support requires a special kind of understanding, especially for the newly-diagnosed.

YANA gives total support to the whole family. We know, because we are prostate cancer survivors. Cancer Staging.

Staging is the process of finding out how much cancer is in a person’s body and where it’s located. It’s how the doctor determines the stage of a person’s cancer.. For most types of cancer, doctors use staging information to help plan treatment and to predict a person’s outlook (prognosis).
