Simulation on transdermal patch for breast cancer therapy by using COMSOL
Breast cancer is the most common form of cancer affecting women in Malaysia. Conventional drug treatment for breast cancer, chemotherapy would destroy the cancer cells because of the medicine targets on rapidly dividing cells. However, healthy cells and tissues in blood, mouth, intestinal tract, nos...

Breast cancer is the most common form of cancer affecting women in Malaysia. Conventional drug treatment for breast cancer, chemotherapy would destroy the cancer cells because of the medicine targets on rapidly dividing cells. However, healthy cells and tissues in blood, mouth, intestinal tract, nose, nails, vagina and hair also divide rapidly, they could be damaged. A more promising technology called transdermal patch has been introduced due to side effects are common expected results from conventional treatment. Therefore, the aim of this study was to treat breast cancer by delivering drug from transdermal patch precisely and safely to targeted cancer cell so that reducing the side effects and dosage of drug used. The objectives of this study were to determine the drug concentration at breast tumor, to investigate the relationship between drug diffusivity and drug delivery efficiency, and to evaluate the efficiency of drug delivery under other parameters (i.e. deepness of tumor, temporal and spatial placement of transdermal patch).
