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
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="holographic.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?
Scientists help immune system find hidden cancer cells Medical Express - October 14, 2019
Cancer cells are masters at avoiding detection, but a new system developed by Yale scientists can make them stand out from the crowd and help the immune system spot and eliminate tumors that other forms of immunotherapies might miss. The new system reduced or eliminated melanoma and triple-negative breast and pancreatic tumors in mice, even those located far from the primary tumor source.

Broken heart syndrome linked with cancer Medical Express - July 17, 2019
Broken heart syndrome, also called takotsubo syndrome, occurs when the heart's main pumping chamber temporarily enlarges and doesn't pump well. Although the syndrome may feel like a heart attack, with chest pain and shortness of breath, there is no heart muscle damage and no blockage in the coronary arteries feeding the heart. Broken heart syndrome can be triggered by emotional or physical stress, but this international study of patients from 26 centers provides the strongest association yet between the syndrome and cancer.
Scientists Develop New Laser That Can Find and Destroy Cancer Cells in the Blood Live Science - June 15, 2019
Cancer cells can spread to other parts of the body through the blood. And now, researchers have developed a new kind of laser that can find and zap those tumor cells from the outside of the skin. Though it may still be a ways away from becoming a commercial diagnostic tool, the laser is up to 1,000 times more sensitive than current methods used to detect tumor cells in blood

A new approach to detecting cancer earlier from blood tests Science Daily - November 15, 2018
Cancer scientists led by principal investigator Dr. Daniel De Carvalho at Princess Margaret Cancer Centre have combined "liquid biopsy," epigenetic alterations and machine learning to develop a blood test to detect and classify cancer at its earliest stages. The findings describe not only a way to detect cancer, but hold promise of being able to find it earlier when it is more easily treated and long before symptoms ever appear.
Researchers measure gene activity in single cells PhysOrg - March 17, 2018
For biologists, a single cell is a world of its own: It can form a harmonious part of a tissue, or go rogue and take on a diseased state, like cancer. But biologists have long struggled to identify and track the many different types of cells hiding within tissues. Researchers at the have developed a new method to classify and track the multitude of cells in a tissue sample. The team reports that this new approach known as SPLiT-seq - reliably tracks gene activity in a tissue down to the level of single cells.
Immune system 'double agent' could be new ally in cancer fight Medical Express - March 16, 2018
Scientists have discovered that an enzyme called TAK1 functions like a "double agent" in the innate immune response, serving as an unexpected regulator of inflammation and cell death. The findings highlight TAK1 inhibition as a potential cancer treatment.
Hope for millions after life-saving AI is revealed that can diagnose prostate cancer as accurately as a doctor Daily Mail - March 16, 2018
Prostate cancer can be diagnosed by new AI just as accurately as any doctor potentially saving millions of lives, new research suggests. Chinese scientists and doctors have developed an artificial intelligence system which they say can accurately diagnose and identify cancerous samples. Experts say it could streamline and eliminate variation in cancer diagnosis and will be particularly useful in areas where there is a lack of trained pathologists. It could also lead to prostate cancer diagnosis being automated in the future.

New Blood Test Can Detect 8 Types of Cancer Live Science - January 22, 2018
Researchers have developed a new blood test that can detect eight common types of cancer, including the notoriously elusive liver and pancreatic cancers. Some day, doctors may be able to use this method to spot cancers in their early stages - before the onset of symptoms - thus improving patients' chances of successful treatment and survival. The test, called CancerSEEK, looks for a number of compounds in the blood that are thought to be early signs of cancer. These include 16 different cancer "driver genes" - genes that are associated with tumors - and eight proteins, according to the study describing the test
Researchers develop a remote-controlled cancer immunotherapy system Medical Express - January 15, 2018
The team developed an innovative approach to use mechanogenetics - a field of science that focuses on how physical forces and changes in the mechanical properties of cells and tissues influence gene expression - for the remote control of gene and cell activations. Researchers used ultrasound to mechanically perturb T cells, and then converted the mechanical signals into genetic control of cells.

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.

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.
