According to Genes & Development, a heterogeneous mass in biology is a tumor with both normal cells and neoplastic cells, which are cells of abnormal growth tissue. Heterogeneous masses are called solid tumors and can be cancerous.Continue Reading
Dr. Barry T. Kahn from HealthTap explains that heterogeneous masses can be malignant or benign. Depending on the size, heterogeneous masses need to be removed and examined for malignancy. Some heterogeneous masses on the ovaries resolve on their own.
Wikipedia goes on to explain that the heterogeneity of cancerous masses makes it difficult to treat cancer because the cells have different forms, gene expressions, motility and metabolism. For example, some of the cells in tumors are cancer stem cells, which can in turn form more tumors. Moreover, there are differences in cancer stem cells. These differences in cancer cells occur in part because of mutations, gene instability, impaired DNA and outside or environmental influences. All of these different and varying cells make the tumor itself heterogeneous and difficult to treat. Drug administration, one treatment option for cancer, does not kill all the different kinds of cancerous cells in a tumor.
Cancers that have heterogeneous masses include breast cancer, prostate cancer, colon cancer, brain cancer, myeloma and leukemia, Wikipedia states.Learn more about Biology
Symptoms of an adrenal gland tumor, which forms as a mass when the growth of normal cells is out of control, include nervousness, heart palpitations, low potassium levels and high blood pressure, states the American Society of Clinical Oncology. Abdominal pain, too much perspiration, headache and anxiety attacks are also possible symptoms.Full Answer >
In biology, probes are general terms for pieces of DNA or RNA that can be used to target specific sequences of DNA or RNA in cells and organisms. Probes can be customized in order to target specific organisms and cells for research.Full Answer >
In biology, feedback inhibition refers to the mechanisms that control certain processes and functions within cells, the body and even the environment. At its most basic, feedback inhibition means that when some sensor gets a certain amount of feedback from the environment, it turns another system on or off.Full Answer >
The function of monocytes is to help the other cells in the blood remove damaged tissue. Monocytes also help destroy cancerous cells.Full Answer >
