Cells are surrounded by a cell membrane (and cell wall in bacteria and plants = a membrane plus some chemically more stable structures, often mixtures of proteins and polysaccharides) and contain all necessary elements to sustain life; proteins, nucleic acids, lipids, minerals, and a diverse class of metabolites.
While all these organelles are found in animal cells, plant cells in addition contain a central vacuole that controls pressure to stabilize the cell and chloroplasts, the site of photosynthesis or light depended biosynthesis of sugars (carbohydrates).
For pancreatic cancer prevention, you should minimize exposure to toxic, carcinogenic substances at home and in the workplace. Avoiding the use of cigarettes is also essential.
High glucose has suppressive effect on the glucagon secretion. But in case of somatostatin, it plays the reverse role, stimulating the production of this hormone.
On the other hand, the secretion of insulin and zinc ions by the beta cells serves to suppress the glucagon synthesis. High glucose level and somatostatin hormone also play a role in suppressing the glucagon secretion.

Insulin: Banting and Best, in early 1920s, identified insulin secreted by endocrine pancreas as an antidiabetic hormone – a milestone in the understanding and treatment of diabetes mellitus. This hormone plays the primary role in maintaining the glucose homeostasis.
Glucagon: An important pancreatic hormone, glucagon plays a critical role in regulating glucose homeostasis. This peptide hormone performs functions that contrast with that of insulin. The former increases the level of blood sugar while the latter lowers the elevated level of blood sugar.
