Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.

Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Treatment plans may include surgery, radiation and/or chemotherapy.
Stereotactic radiosurgery could be more effective for patients with few metastatic brain tumors

Stereotactic radiosurgery could be more effective for patients with few metastatic brain tumors

Patients with three or fewer metastatic brain tumors who received treatment with stereotactic radiosurgery (SRS) had less cognitive deterioration three months after treatment than patients who received SRS combined with whole brain radiation therapy (WBRT). [More]

Exposure to infections in early life not linked to higher mortality risk during adulthood

Exposure to infections in early life not linked to higher mortality risk during adulthood

A new biological study by the University of Stirling has found that exposure to infections in early life does not have long-lasting consequences for later-life survival and reproduction. [More]
Study finds positive changes in patient's personal outlook, quality of life post dementia diagnosis

Study finds positive changes in patient's personal outlook, quality of life post dementia diagnosis

Results from a study of patients with a diagnosis of mild cognitive impairment or early dementia indicates that their outlook isn't as dark as expected. [More]
Liquid biopsies hold potential for detecting NSCLC EGFR mutations, predicting cancer recurrence

Liquid biopsies hold potential for detecting NSCLC EGFR mutations, predicting cancer recurrence

Three manuscripts published in the recent issue of the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer, explored the versatility of liquid biopsies by identifying EGFR mutations using circulating tumor DNA (ctDNA) in urine and plasma and examining circulating tumor cells (CTCs) in plasma to predict the risk of lung cancer recurrence after surgical resection.

Researchers identify genetic variants linked to radiotherapy side-effects in prostate cancer patients

A new study involving researchers from The University of Manchester looked at the genetic information of more than 1,500 prostate cancer patients and identified two variants linked to increased risk of radiotherapy side-effects. [More]

New study uncovers way to characterize black box of malignant melanoma

New study uncovers way to characterize black box of malignant melanoma

When malignant melanoma metastasizes to the brain, it is a death sentence for most patients. Metastatic melanoma is the deadliest of the skin cancers and the mechanisms that govern early metastatic growth and interactions of metastatic cells with the brain microenvironment remain shrouded in mystery.

Study reveals unexpected process for acquiring chemoresistance in breast cancers

Study reveals unexpected process for acquiring chemoresistance in breast cancers

A laboratory study has revealed an entirely unexpected process for acquiring drug resistance that bypasses the need to re-establish DNA damage repair in breast cancers that have mutant BRCA1 or BRCA2 genes. [More]
