Types of tumors
Every tumor is not cancerous. It's depending upon whether it is capable of invading other tissues and cause harm, or it can silently remain at one place without harming other cells in the vicinity .
- Well-differentiated Cells
- Usually not life-threatening
- do not spread
- slow growth
- Undifferentiated Cells
- Capable of spreading
- Cells are non-functional
- Cells differ in size and shape
Types of cancers
Carcinomas are cancers of epithelial tissues that means, carcinomas are developed in the skin and tissue lining of the organs like prostate, breast, colon, pancreas, lungs and so on.
Chemotherapy is currently the most effective and widespread treatment. The problem is that it delivers substances into the body that destroy cancer cells by considerably weakening the body.This is where research on nanotechnology could change everything, by making it possible to address drugs directly to infected cells, via a vectorization process. The treatment gains in efficiency and above all, the patient does not suffer from the side effects induced by conventional chemotherapy.
typical side effects of current treatments
Hair loss, weakness and appetite changes.
Easy bruiding and bleeding , loss of bone mass
TIMELINE of discoveries
IBM (Development of an ultra-fast lithography to create 3D nanoscale textured surface)
Nadrian Seeman (DNA structures fold into 3D rhombohedral crystals).
In medicine, certainly in the diagnosis and treatment of cancer. Nanoparticles are known as contrast agents and could be very useful in identifying tumors in specific areas of the body or in monitoring the direction of tumor cells. Nanotechnology can help to make cancer treatments safer and more precise. Specially designed nanoparticles deliver medicines like chemotherapy straight to the tumor.This stops the drugs from damaging healthy tissues around the tumor.
If we can reduce the cost and improve the quality of medical technology through advances in Nanotechnology, we can more widely address the medical conditions that are prevelant and reduce the level of human suffering.
