Cancer, also known as a malignant tumor or malignant neoplasm, is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. Not all tumors are cancerous; benign tumors do not spread to other parts of the body.Possible signs and symptoms include: a new lump, abnormal bleeding, a prolonged cough, unexplained weight loss, and a change in bowel movements among others. While these symptoms may indicate cancer, they may also occur due to other issues. There are over 100 different known cancers that affect humans. Read more
Lawsuits for Talcum Powder is Being Linked to Ovarian Cancer - For many decades, women have used talcum powder to relieve discomfort, odor and moisture in the vaginal area. The question of whether or not this practice leads to ovarian cancer is an area of concern for everyone. Unfortunately for some women, the investigation comes too late; they already have suffered.
We all have the potential to get cancer. When the soul is burned out and the person can't cope with life, that energy moves from the soul level, to the emotional level where we process and create illnesses and accidents to just STOP. The area of the body affect by the cancer, is a direct reflection of the emotional problems. For example, a woman challenged by romantic love will develop cancer in the chest or breast area.
Everything we do in this A HREF="reality.html">reality is programmed into our genetic code, as if a time capsule, that starts ticking at the time of conception. From then on, we just play it out our roles. I know most people believe in Free Will, but if that were the case, how much different would your life - and everyone else's be?
Many people use an number of holistic remedies and combine organic foods with a proper diet to cure cancer - none successful or their cure would eradicate all cancers. At best they delay the spread of cancer, but are generally not a long-term care. Used along with western medicine, holistic cures can be helpful. The use of marijuana to control nausea after chemotherapy is widely practiced. Conspiracies theorists believe the governments are holding back cures and in some cases develop diseases.
FDA Clears First Cancer Drug Based on Genetics of Disease, Not Tumor Location Scientific American - May 24, 2017
Merck & Co's immunotherapy Keytruda chalked up another approval on Tuesday as the U.S. Food and Drug Administration said the cancer medicine can be used to treat children and adults who carry a specific genetic feature regardless of where the disease originated. It is the first time the agency has approved a cancer treatment based solely on a genetic biomarker.
Surprising link between blood sugar, brain cancer found Science Daily - May 3, 2017
New research further illuminates the surprising relationship between blood sugar and brain tumors and could begin to shed light on how certain cancers develop. While many cancers are more common among those with diabetes, cancerous brain tumors called gliomas are less common among those with elevated blood sugar and diabetes.
Most cancer mutations are due to random DNA copying 'mistakes' Science Daily - March 23, 2017
Scientists report data from a new study providing evidence that random, unpredictable DNA copying 'mistakes' account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model based on DNA sequencing and epidemiologic data from around the world.
A cancer's surprise origins caught in action Science Daily - February 5, 2016
Researchers have, for the first time, visualized the origins of cancer from the first affected cell and watched its spread in a live animal. Their work could change the way scientists understand melanoma and other cancers and could lead to new, early treatments before the cancer has taken hold.
New method detects early breast cancer via urine Science Daily - June 11, 2015
Medical researchers have developed an approach for detecting breast cancer by means of urine samples. The method involves determining the concentration of molecules that regulate cell metabolism and that are often dysregulated in cancer cells. These molecules, referred to as microRNAs, enter into the urine over the blood. By determining the composition of microRNAs in the urine, the scientists succeeded in establishing with 91 percent accuracy whether a test subject was healthy or diseased.
The Three Reasons So Many People are Getting Cancer Live Science - June 4, 2015

Breast Cancer Genes: How Much Risk Do BRCA Mutations Bring? Live Science - April 8, 2015
Women with mutations in the BRCA1 and BRCA2 genes are at increased risk for breast and ovarian cancer, but a woman's exact cancer risk may vary greatly depending on exactly how her gene is mutated, or changed from its original form. A new study identifies a number of mutations in the BRCA1 and BRCA2 genes that may help doctors provide women with more precise estimates of their cancer risk. "We have women who are 70 and 80 years old who have BRCA1 [or] BRCA2 mutations and have never developed cancer of any kind," said study researcher Timothy Rebbeck, a professor of epidemiology at the University of Pennsylvania's Perelman School of Medicine. "If we can give more precise risk estimates," this may help women with their decisions, Rebbeck said.
Cancer turns blood vessels over to its cause PhysOrg - December 1, 2014
Cancer requires a blood supply to deliver the nutrients and oxygen it needs to grow and survive. It had been thought that tumors create the blood supply they need by stimulating the formation of new blood vessels, a process called angiogenesis. But this no longer appears to be the only process going on. Some tumors seem to acquire their blood supply by taking over existing blood vessels, co-opting them for their cancerous growth.
Genetics of cancer: Non-coding DNA can finally be decoded PhysOrg - July 23, 2014
Cancer is a disease of the genome resulting from a combination of genetic modifications (or mutations). We inherit from our parents strong or weak predispositions to developing certain kinds of cancer; in addition, we also accumulate new mutations in our cells throughout our lifetime. Although the genetic origins of cancers have been studied for a long time, researchers were not able to measure the role of non-coding regions of the genome until now. A team of geneticists from the University of Geneva (UNIGE), by studying tissues from patients suffering from colorectal cancer, have succeeded in decoding this unexplored, but crucial, part of our genome.
Viral relics show cancer's 'footprint' on our evolution Science Daily - July 23, 2014
Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species. The team found that as animals increased in size they 'edited out' potentially cancer-causing relics from their genomes so that mice have almost ten times as many ERVs as humans. The findings offer a clue as to why larger animals have a lower incidence of cancer than expected compared to smaller ones, and could help in the search for new anti-viral therapies.
Why an extra helix becomes a third wheel in cell biology PhysOrg - July 3, 2014
In a literal scientific twist, researchers are finding examples of a third strand that wraps itself around RNA like a snake, a structure rarely found in nature. Researchers recently have discovered evidence of a triple helix forming at the end of MALAT1, a strand of RNA that does not code for proteins. This extra strand of RNA, which is seen in the accompanying movie, prevents degradation of MALAT1. The formation of a triple helix explains how MALAT1 accumulates to very high levels in cancer cells, allowing MALAT1 to promote metastasis of lung cancer and likely other cancers.
Discovery of a primordial cancer in a primitive animal PhysOrg - June 24, 2014
Cancer is as old as multi-cellular life on earth and will probably never be completely eradicated. The causes of tumors are the so-called cancer genes. Data predicted that the first multi-cellular animals already had most of the genes which can cause cancer in humans.
Doctors say gene therapy helping blood cells fight cancer FOX - December 8, 2013
In one of the biggest advances against leukemia and other blood cancers in many years, doctors are reporting unprecedented success by using gene therapy to transform patients' blood cells into soldiers that seek and destroy cancer.
New Plan of Attack in Cancer Fight: Two-Drug Combination, Under Certain Circumstances, Can Eliminate Disease Science Daily - July 19, 2013
New research conducted by Harvard scientists is laying out a road map to one of the holy grails of modern medicine: a cure for cancer. As described in a paper recently published in eLife, Martin Nowak, a professor of mathematics and of biology and director of the Program for Evolutionary Dynamics, and co-author Ivana Bozic, a postdoctoral fellow in mathematics, show that, under certain conditions, using two drugs in a "targeted therapy" -- a treatment approach designed to interrupt cancer's ability to grow and spread -- could effectively cure nearly all cancers.

Childhood leukemia cell culprit discovered BBC - January 17, 2008
A study of four-year-old twin girls has identified a rogue cell that is the root cause of childhood leukemia. The finding could mean more specific and less intensive treatments for all children with the blood cancer. Both twins were found to have the "pre-leukemic" cells in their bone marrow, although to date only one has developed leukemia. UK researchers reported in Science that a second genetic mutation is needed for full-blown disease to develop. Leukemia occurs when large numbers of white blood cells take over the bone marrow leaving the body unable to produce enough normal blood cells.
Genome study finds 100 new cancer genes Guardian - March 7, 2007
Scientists have found more than 100 new genes that can cause cancer if they become mutated. The discovery was part of the largest survey of the human genome to date, which also suggests that the number of cancer genes is far larger than previously thought. All cancers are thought to be caused by DNA mutations in specific genes. This is from a full spec of around 25,000 genes in the human genome. The cancer genes have been painstakingly identified during more than 25 years of research. But new technology is speeding up the process, allowing scientists to systematically identify all the genes in a cancer cell. These gene sequences can then be compared to healthy cells to identify differences in DNA.
Experts crack cancer 'gene codes' BBC - October 30, 2006
US scientists have cracked the entire genetic code of breast and colon cancers, offering new treatment hopes. The genetic map shows that nearly 200 mutated genes, most previously unknown, help tumors emerge, grow and spread. The discovery could also lead to better ways to diagnose cancer in its early, most treatable stages, and personalized treatments. The mutated genes in breast and colon cancers were almost completely distinct, suggesting very different pathways for the development of each of these cancer types. Each individual tumor appeared to have a different genetic blueprint, which could explain why cancers can behave very differently from person to person, the scientists said.
