If you think that cholesterol is bad for your heart only, then you will have to rethink about the assumption as according to an alarming research, 'bad'cholesterol helps cancer spread around the body.
According to sources, this is because cholesterol regulates the machinery that controls the movement of cells in the body.
Most of the cells in our bodies stick to neighbouring cells through the help of molecules on their surface known as integrins that helps cells stick together.
According to Thomas Grewal, an associate professor from University of Sydney, "Bad cholesterol (low-density lipoprotein or LDL) controls the trafficking of tiny vessels which also contain these integrins, and this has huge effects on the ability of cancer cells to move and spread throughout the body."
Unfortunately, integrins also help cancer cells that have broken away from a cancerous tumour to take root elsewhere in the body.
In contrast, high levels of "good"cholesterol keeps integrins inside cells and may, therefore, protect against cancer cell spread.
Malignant cancer cells are known to take up increased amounts of bad cholesterol, Grewal noted in a paper published in the journal Cell Reports.
According to Grewal, people with common cancers such as breast, prostate, lung and liver cancers often have low LDL levels because the cholesterol has been absorbed by the cancer cells which need it to grow and spread.
