Cancer is one of most devastating diseases of the world. Every year, more than 8 million people die of cancer worldwide. Despite advances in medicine, there is still no cure for cancer.
Treatments
Fortunately, modern medicine has come a long way in its fight against cancer. There are several effective treatments against this terrible disease, such as chemotherapy, radiation therapy, stem cell therapy and drugs that help fight cancer.
chemotherapy It is one of the most common treatments against cancer, consists of administering drugs that destroy cancer cells. It is generally used to treat cancers of internal organs, such as the lung, stomach, liver and lymphatic system. It can also be used to treat skin and eye cancers.
Radiation therapy is another effective treatment. for cancer, by exposing cancer cells to ionizing radiation. This radiation destroys cancer cells and can be used to treat cancers of internal and external organs.
stem cell therapy has become a promising treatment for cancer. The method is the transfer of healthy stem cells to a cancer patient. These stem cells are responsible for repairing and replacing cancer cells.
For last, medications are also an effective treatment against cancer. They can help kill cancer cells, stop their growth, prevent the disease from recurring, and reduce side effects.
cancer vaccine
Many scientists are working hard to find a solution to cancer, but one question that remains unanswered is whether there will ever be a cancer vaccine. One of the major problems with creating a purported vaccine is that cancer is a very complex disease. It is not a single disease, but many different variations. This means that although vaccines may be developed for some of them, there’s no way of knowing if they will work for all of them.
Another problem is the difficulty finding an antigen for the vaccine. Antigens are substances that can stimulate the immune system to fight disease. Although some cancer-related antigens have been identified, specific antigens for disease prevention have not yet been identified.
On the other hand, there is a many contributing environmental factors to the development of cancer. These include factors such as pollution, chemicals, smoking and alcohol. Which means that, as long as there are environmental factors, a vaccine won’t be able to prevent cancer. However, despite these challenges, scientists and doctors are working hard to find a solution. Many researchers believe a cancer vaccine is possible, but there is still a lot of work to be done before it becomes a reality.
