The process is typically called “
The immune system can help to fight cancer
Some cells of the immune system can recognise cancer cells as abnormal and kill them. But this may not be enough to get rid of a cancer altogether. Some treatments aim to use the immune system to fight cancer.
Remission can be partial or complete. In a complete remission, all signs and symptoms of cancer have disappeared. If you remain in complete remission for 5 years or more, some doctors may say that you are cured. Still, some cancer cells can remain in your body for many years after treatment.
Many people with cancer feel sad. They feel a sense of loss of their health, and the life they had before they learned they had the disease. Even when you're done with treatment, you may still feel sad. This is a common response to any serious illness.
Most cancers that are going to come back will do so in the first 2 years or so after treatment. After 5 years, you are even less likely to get a recurrence. For some types of cancer, after 10 years your doctor might say that you are cured. Some types of cancer can come back many years after they were first diagnosed.
Occasionally, however, these cells manage to sneak under the radar, reproducing until they grow into a full-blown tumour. By the time the cancer has reached the attention of doctors, unaided recovery is highly unlikely: overall, just one in 100,000 cancer patients are thought to shed the disease without treatment.
Sometimes symptoms affect specific areas of the body, such as our tummy or skin. But signs can also be more general, and include weight loss, tiredness (fatigue) or unexplained pain. Some possible signs of cancer, like a lump, are better known than others.
Many patients with stage 1 cancer live for years as long as the cancer is treated and managed. A few factors to keep in mind: Many treatments are available to help fight cancer. The body's response to treatment may differ from other patients' experience.
Silent cancers are cancers that do not have any noticeable early symptoms. Some silent cancers include breast cancer, ovarian cancer, colorectal cancer, Pancreatic cancer and lung cancer.
For some people, the cancer can't be controlled anymore and spreads to healthy tissues and organs. Cancer cells take up the needed space and nutrients that the healthy organs would use. As a result, the healthy organs can no longer function. For other people, complications from treatment can cause death.
The Fastest Killing Cancer
If defining "fastest-killing" cancer is based on which cancer has the worst 5-year relative survival rate, then it would be a tie between pancreatic cancer and malignant mesothelioma (a relatively rare cancer in the U.S. with about 3,000 cases a year).
Cytotoxic T lymphocytes (CTL) are the cells that recognize and destroy cancer cells, and they're first activated in tumor-draining lymph nodes. From there, they enter the bloodstream to reach tumors and battle malignant cells. Tumors are very hostile environments for CTLs, however.
Tyrosine kinase inhibitors (TKIs) block chemical messengers (enzymes) called tyrosine kinases. Tyrosine kinases help to send growth signals in cells, so blocking them stops the cell growing and dividing. Cancer growth blockers can block one type of tyrosine kinase or more than one type.
Stage 4 cancer usually can't be cured. In addition, because it's usually spread throughout the body by the time it's diagnosed, it is unlikely the cancer can be completely removed. The goal of treatment is to prolong survival and improve your quality of life.
Stage 4 is the most severe stage of cancer, with the highest risk of mortality. However, many factors affect a person's life expectancy, including the type of cancer.
Stage 0 cancers are still located in the place they started. They have not spread to nearby tissues. This stage of cancer is often curable. Surgery can usually remove the entire tumor.
Here is a list of some symptoms you might have if you have cancer related fatigue: lack of energy – you may just want to stay in bed all day. feeling you just cannot be bothered to do much. sleeping problems such as unable to sleep or disturbed sleep.
Cancer is a group of diseases that we may never be able to cure completely, but scientists are optimistic that vaccines, personalised medicine and smart lifestyle choices will help prevent and treat a much greater proportion of cases than currently happens.
