For example, a collection of fluid would meet the definition of a tumor. A cancer is a particularly threatening type of tumor. It is helpful to keep these distinctions clear when discussing a possible cancer diagnosis.

The cells in a neoplasm usually grow more rapidly than normal cells and will continue to grow if not treated. As they grow, neoplasms can impinge upon and damage adjacent structures.

The term neoplasm can refer to benign usually curable or malignant cancerous growths. This is a general term that can refer to benign generally harmless or malignant cancerous growths. A benign tumor is usually localized, and does not spread to other parts of the body.

Most benign tumors respond well to treatment.

Tumor suppressor genes

However, if left untreated, some benign tumors can grow large and lead to serious disease because of their size. Benign tumors can also mimic malignant tumors, and so for this reason are sometimes treated.

They are often resistant to treatment, may spread to other parts of the body and they sometimes recur after they were removed. What is Pancreatic Cancer? Cancer of the pancreas is a malignant neoplasm that arises in the pancreas.

It strikes approximately 9 out of everypeople every year in the United States and is one of the deadliest forms of cancer. It is estimated that this year 45, Americans will be diagnosed with cancer of the pancreas. An almost equal number of patients some diagnosed previous to this year will die from pancreatic cancer during this year.

Cancer of the pancreas is not one disease. In fact, as many as twenty different tumors have been lumped under the umbrella term "cancer of the pancreas. An understanding of the different types of neoplasms of the pancreas is required for rational treatment.

Cancers of the pancreas can be broadly classified as: Primary- Primary cancers are those that arise in the pancreas itself. Metastatic- tMetastatic cancers are cancers that arise in other organs and only later spread to the pancreas. These are usually not considered a pancreatic cancer, instead they are considered cancers of the organs from which they arose.

In the vast majority of cases the term "cancer of the pancreas" refers to primary cancers of the pancreas — cancers that arose in the pancreas.

Primary cancers of the pancreas can be broadly subgrouped into those that look like endocrine cells under the microscope have endocrine differentiation and those that look like exocrine cells under the microscope have exocrine differentiation.Apparent Diffusion Coefficient Histograms of Human Papillomavirus–Positive and Human Papillomavirus–Negative Head and Neck Squamous Cell Carcinoma: Assessment of Tumor Heterogeneity and Comparison with Histopathology.
