Using concepts of physics and mathematics, researchers at the University of Michigan Comprehensive Cancer Centre have developed a mathematical model to understand how cancer develops - and how to stop it.
Traditional cancer biology involves taking a sample of cells and holding them in time so they can be studied. Then the researchers look at that slice of cells to understand what signals and pathways are involved.
Breast Cancer - Causes, Risks, Symptoms, Diagnosis, Staging, Treatment, Prevention & Prognosis
Breast cancer is a cancer that affects the breasts or mammary glands. Early detection and lifestyle changes help in controlling breast cancer.

"The living cell is really a dynamic process. We need to consider the properties of physics to help us understand these data. In order to develop a drug directed against a given molecule that has real hope of treating cancer, we need to understand how that molecule is sitting in the cell, interacting with other molecules," said Merajver, professor of internal medicine at the U-M Medical School.
They have now developed a sophisticated mathematical model to help researchers apply these concepts to cancer.
About Cancer in Women
Cancer is one of the frequently talked about and most feared disease that falls under the genre of lifestyle diseases that have evolved, rather rapidly, in the past two decades.

By understanding the full complexity of signaling pathways, researchers can better target treatments and identify the most promising potential new drugs.

Liver Cancer
Liver is the largest organ inside the human body. It performs 500 different functions and processes 720 liters of blood per day. The important functions of the liver, the development of liver cancer and it’s symptoms are presented in this interactive.

That implies new considerations for developing drugs to inhibit major growth and metastasis pathways in cancer. This crosstalk was missed by conventional methods.

"When you make simplifying assumptions, you always run the risk of eliminating critical aspects of your system, but you have no way of knowing what was discarded. When you simplify, you don’t know exactly what you’re throwing away because you never looked at the complex case," said Merajver.
Mathematical modelling allows researchers to look at the complex case more thoroughly.
"To understand how the laws of physics can be applied to biological systems is a new frontier," she said.
The researchers could successfully get the journal Cancer Research to add a new regular section to the twice-monthly journal precisely focused on mathematical modelling.
