The submucosa (or tela submucosa) is a thin layer of tissue in various organs of the gastrointestinal, respiratory, and genitourinary tracts. It is the layer of dense irregular connective tissue that supports the mucosa (mucous membrane) and joins it to the muscular layer, the bulk of overlying smooth muscle (fibers running circularly within layer of longitudinal muscle).
In the United States in 2012, it was estimated that there was an incidence of 12,000 new cases, and 1,300 deaths, from cancer among children 0 to 14 years of age. [64] Cancer is the second leading cause of death in males and fourth in women under the age of 20 in the United States. The survival rate of children with cancer has improved since ...
Progression of epithelial cancer often relies on deep and regional lymph node invasion. [12] The lamina propria, being one of the barriers to the submucosa, is an area where epithelial cancer invasion is of significance since lymphatic invasion is an independent predictor of lymph node metastasis , especially in gastric cancer .

The submucosa is the tissue that connects the mucosa to the muscle outside the tube. The glands themselves are quite complex. The mucus factory is at the bottom, in the submucosa, it is composed of many little sacs (acini) where the mucus originates. Each sac (acinus) has one end that can open and close (dilate) to allow the mucus out.
The American Cancer Society recommends that all adults over 45 be tested regularly for colon cancer, even if they have no symptoms. People older than 50 are still at a greater risk of developing ...
Signs and symptoms are not mutually exclusive, for example a subjective feeling of fever can be noted as sign by using a thermometer that registers a high reading. [7] Because many symptoms of cancer are gradual in onset and general in nature, cancer screening (also called cancer surveillance) is a key public health priority. This may include ...
The subserosa has clinical importance particularly in cancer staging (for example, in staging stomach cancer [1] or uterine cancer). The subserosa ( sub- + serosa ) is to a serous membrane what the submucosa ( sub- + mucosa ) is to a mucous membrane .
