Certain fruits, vegetables, nuts, beans, oats, whole grains, spices and teas provide unique benefits not found in other foods. These benefits help reduce the risks of certain cancers and can even slow tumor growth and recurrence. Most of these plant-based foods provide plenty of other health benefits too.
Cytotoxic T lymphocytes (CTL) are the cells that recognize and destroy cancer cells, and they're first activated in tumor-draining lymph nodes.
Ketogenic diets selectively starve tumors by providing the fat and protein that otherwise could not be used by glucose-dependent tumor cells.
Tumours have been known to disappear spontaneously, in the absence of any targeted treatment, usually after an infection (bacterial, viral, fungal or even protozoal).
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.
Removing a tumor is a common type of cancer surgery. This may also be called a "resection" or "excision." Your doctor usually takes out the tumor and some of the healthy tissue near it. The tissue around the tumor is called the margin. Tumor removal generally requires a larger incision, or cut, than a biopsy.
But as a tumour grows, it needs more blood to bring oxygen and other nutrients to the cancer cells. So cancer cells send signals for a tumour to make new blood vessels. This is called angiogenesis and it is one of the reasons that tumours grow and get bigger.
A study published in 2021 found that exercise may help halt or slow the growth of tumors.
Treatment. There are no cures for any kinds of cancer, but there are treatments that may cure you. Many people are treated for cancer, live out the rest of their life, and die of other causes. Many others are treated for cancer and still die from it, although treatment may give them more time: even years or decades.
Still, some cancer cells can remain in your body for many years after treatment. These cells may cause the cancer to come back one day. For cancers that return, most do so within the first 5 years after treatment. But, there is a chance that cancer will come back later.
The 5-year relative survival rate for a cancerous brain or CNS tumor is almost 36%. The 10-year survival rate is over 30%. The survival rates for a brain tumor vary based on several factors.
Dead cancer cells are as tasty to a phagocyte as any other type of dead cell. The dead cells cannot “re-enter the bloodstream” once they've been digested by macrophages, because the digestion process breaks down the chunks into individual chemical components (amino acids, lipids, sugars, minerals).

In contrast, in a complete remission the tumor shrinks so much that at the end of treatment there is no longer any clinical evidence of disease by physical examination, by biochemical and radio- graphic evaluation, or by the patient's symptoms.
Sometimes, cancer treatment can go on for an extended period of time. Many people receive cancer treatment for months, years, or even the rest of their lives.
Vitamin D may decrease tumor invasiveness and propensity to metastasize, leading to reduced cancer mortality. Higher serum 25-hydroxyvitamin D (25[OH]D) levels at diagnosis have been linked to longer survival in cancer patients.
Zinc's potential as a cancer therapy stems from its specific role in preserving the proper function of the p53 gene, a protein located in the nucleus of all cells in the body. Under normal conditions, p53 suppresses tumors and keeps cancer at bay.
Radiotherapy involves using controlled doses of high-energy radiation, usually X-rays, to kill the tumour cells. Chemotherapy is less frequently used to treat non-cancerous brain tumours. It's a powerful medicine that kills tumour cells, and can be given as a tablet, injection or drip.
Commonly known as soursop or Lakshman Phal in India, this fruit is a native of Brazil. Known to be god's gift to humanity, it is a miracle food for cancer patients.
