Up to half of people ignore physical symptoms and genes that may be the first indication of cancer development. According to a study by Cancer Research UK, described in the British newspaper The Independent. The reason that so many people do not go to the doctor is, according to the study, "fear of wasting the doctor's time."
A combination of two already approved drugs can cause cancer cells to develop into harmless fat cells, according to new research from scientists at the University of Basel in Switzerland. One agent, rosiglitazone, is used in type 2 diabetes and increases insulin sensitivity.
Cancer develops in a process of often 20 to 40 years. A cell mutates gradually, giving it dangerous properties. After 10 to 15 mutations in a certain order that reinforce each other's harmful effect, a cancer cell can arise. The mutated cells form a tumor that oppresses and destroys healthy tissue.
Fatigue, nausea, diarrhea and heart attacks. Those are the side effects of chemotherapy. Scientists are now trying to tackle them with 3D-printed blood filters that have been tested on pigs. Although chemotherapy can save seriously ill cancer patients, there are many disadvantages to the treatment.
One in seven cancer patients uses alternative therapies. And that is not harmless. Patients who exchange traditional therapy for an alternative are five times as likely to die within five years. And even the patients who follow the therapist's therapies are in the danger zone if they also use herbal medicines.
Breast cancer alone has 11 variants, which can also be subdivided into different categories. No two patients have exactly the same type of tumor, and therefore they respond differently to various therapies. This wide variation has arisen because cancer can occur in different cell types - in the breast, for example, in the mammary glands or connective tissue.
It takes time to determine if someone has cancer. First doctors discover cell changes in the body. Then they take a sample and examine it to make the diagnosis. There is no method to quickly test the entire body for cancer. But it is coming - based on gold.
Thousands of potential drugs are tested in the lab. Only a few are eligible to be tested on humans. But the selection process is not optimal. Substances that should never have been tested on humans have slipped through, while therapies that could have saved lives have been rejected.
Bacterial scientists have mapped a whole new type of cells. This can be decisive in the fight against cancer. When bacteria divide, a new, functional bacterium does not always arise. Sometimes the division only results in a much smaller cell, which lacks all kinds of vital mechanisms.
In 1999, a promising drug made short work with tumors on test mice. The therapy, SPI-77, worked better than regular chemotherapy and, moreover, had fewer side effects. Soon a pharmaceutical company was hoping to put millions of people into testing the drug, but the tests were quickly discontinued.
You may already have a bacterium on your skin that protects you against skin cancer. American researchers from the University of California discovered that some people carry staphylococci that have that beneficial property. Cancer cells cannot divide The researchers studied various strains of the Staphylococcus epidermidis, which lives on our skin in various variants.
For people with breast cancer, it is crucial that tumors in the breast are discovered and treated before the cancer can spread. Researchers at Johns Hopkins University in the US discovered that certain cells in the breasts of women metastases probably occur. Most tumors in the breast occur along the inside of the milk ducts, which connect the mammary glands with the nipple.
The scientists thought they had made a calculation error when delving into the research results. But there was no error. Their experiments with mice showed that they had killed many more cancer cells than in previous treatments. Only tumor gets chemo With so-called organic nano couriers, the researchers managed to deliver chemotherapy directly to the brain tumor - without surgery and without damaging the surrounding tissue.
One of the biggest headaches for doctors is how they can detect tumors before they are large and deadly. New research shows that even small nodules are already visible in your blood long before they can be detected by other methods. Blood test betrays illness early on As your blood is pumped to your legs, through your fingers and along your organs, your body's transport system picks up some lifters along the way.
Some natural substances from medicinal plants can kill cancer cells. One is a so-called terpenoid called ingenol-3-angelate, which works against skin cancer. This substance only occurs in the resin of the Euphorbia peplus plant and is virtually impossible to produce in large quantities in the lab.
Scientists want to change your immune system into a targeted killing machine that removes cancerous tumors from your body on your own. The secret behind this treatment is the revolutionary gene technology CRISPR. CRISPR consists of three molecular 'scissors' that can cut certain genes in a cell and replace them with new ones.
Cancer cells control the other cells in the body on several points: They live longer and divide faster than normal cells. And researchers have long suspected that the aggressive disease cells have even more special properties, with which they can spread quickly, so that tumors arise everywhere in the body.
Throughout your life, your immune system eradicates potential cancer cells. That means that the risk of cancer is quite small despite everything. But if the cancer cells are able to inhibit the immune system, then a tumor can continue to grow. The immune system consists of a number of different cell types.
A handfull. So few women think the Australian authorities will have to treat for cervical cancer in 10 to 20 years. The vast country is well on its way to eradicating this cancer, according to research recently published by the International Papillomavirus Society.
Only about 7 percent of patients with pancreatic cancer live longer than five years after being diagnosed. The unusually high mortality rate is mainly due to the fact that the disease is only discovered when it has had years to develop. Rapid cancer diagnosis is very important because cancer cells are more susceptible to therapies in the early stages.
Cancerous tumors depend on the supply of blood. They die without blood. Researchers at Arizona State University, USA, and the National Center for Nanoscience and Technology, China, developed a robot with a mission: choke growths by cutting the blood. The robot was built using a technology that gives DNA strands a structure that the researchers want.
