Like that Center for Cancer Registry Data 43% of women are approximately every second man (51%) in Germany affected by cancer over the course of their lives. Various factors influence whether cancer develops and how it progresses. The height Affect rate ensures that researchers around the world are constantly working on new methods to combat tumors. International researchers were now able to… develop new drug.
The incidence of cancer: The new approach should help
In medicine, the term “cancer” refers to a malignant tissue neoplasm. Like that German Cancer Research Center explains, the tumor cells of a cancerous tumor multiply uncontrolled. Some of them grow into neighboring tissue. There they destroy healthy tissue and form daughter tumors. These will Metastases called. The cancerous tumors that first form in the body are called primary tumors. These are often easy to treat. For example, they can often be completely removed with surgery or reduced in size with chemotherapy or radiation.
Die second most common cause of death There is still cancer in Germany. This is often due to the new growths, the metastases. The new tumors can only be treated medically difficult to treat. They often lead to the death of cancer patients. In 2019, according to the Center for Cancer Registry Data, there were a total of 502.66 new cancer cases. The most commonly diagnosed types are breast cancer, colon cancer, prostate cancer and lung cancer. The Chances of survival depend largely on the type of cancer.
Researchers aim to find a drug that… also kill metastases can. The newly developed drug contains Nanoparticles. Nanoparticles are tiny particles that accumulate in the tissue of a known tumor. Because this diseased tissue rather holey is, the particles can attack it ideally.
Treating cancer using nanoparticles
The nanoparticles used are coated with a substance that sensitive to light is. When they are irradiated with light, they absorb the energy from the light. This will make them activated. Generate activated nanoparticles chemical reaction, which in turn can destroy tumor cells. This is why the tumor cells are destroyed oxidative stressthat the nanoparticles trigger in them. Under the term “oxidativer Stress” means a metabolic situation in which there is an imbalance. The imbalance here is between free radicals and radical scavengers. Oxidative stress can lead to damage to cells and metabolic problems. It further activates this Immune system. The immune cells can now recognize the diseased industry as foreign and fight it.
On the one hand, the nanoparticles attack the cancer cells in the tumor, but on the other hand they also attack all cells in the body that are similar to them. These include the daughter tumors, i.e Metastases. Three pilot projects with nanoparticles are currently underway Washington University in den USA. So far there is still no concrete evidence that the drug actually works as planned. It probably will several years It will take time for studies to prove its effectiveness.
Nanotechnology is a reason for hope for patients, relatives and doctors. She probably will an important role in the future play in the treatment of cancer. The federal government points out the potential of nanotechnology in an article. In the future it would even be possible for nanoparticles to be used Active ingredients against certain tumors specially programmed become. In this way, they could distinguish between healthy and diseased tissue, target the active ingredient specifically against the tumor cells and thus potentially replace chemotherapy.
Conclusion: Nanotechnology offers new hope
So far there is different treatment options for cancer, including surgery, radiation therapy and chemotherapy. Research is constantly working on new methods. The Nanotechnology is a promising method in the treatment of cancer and could play an important role in the future. However, there still have to be further investigations and studies be carried out to prove the effectiveness of drugs containing nanoparticles.
