The hallmarks of cancer were originally six biological capabilities acquired during the multistep development of human tumors and have since been increased to eight capabilities and two enabling capabilities. The idea was coined by Douglas Hanahan and Robert Weinberg in their paper "The Hallmarks of Cancer" published January 2000 in Cell. [1]
For cancer in the United States, the average five-year survival rate is 66% for all ages. [5] In 2015, about 90.5 million people worldwide had cancer. [18] In 2019, annual cancer cases grew by 23.6 million people, and there were 10 million deaths worldwide, representing over the previous decade increases of 26% and 21%, respectively. [6] [19]
The activity of c-Src has been best characterized in colon cancer. Researchers have shown that Src expression is 5 to 8 fold higher in premalignant polyps than normal mucosa. [24] [25] [26] The elevated c-Src levels have also been shown to have a correlation with advanced stages of the tumor, size of tumor, and metastatic potential of tumors ...

Mutated p53 is involved in many human cancers, of the 6.5 million cancer diagnoses each year about 37% are connected to p53 mutations. [30] This makes it a popular target for new cancer therapies. Homozygous loss of p53 is found in 65% of colon cancers, 30–50% of breast cancers, and 50% of lung cancers.
Since the 1970s, dozens of oncogenes have been identified in human cancer. Many cancer drugs target the proteins encoded by oncogenes. [2] [4] [5] [6] Oncogenes are a physically and functionally diverse set of genes, and as a result, their protein products have pleiotropic effects on a variety of intricate regulatory cascades within the cell.
Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology. In some centers "hematology/oncology" is a single subspecialty of internal medicine while in others they are considered separate divisions (there are also surgical and radiation oncologists).
Daily long-term use of high voltage (5.0 V) electronic cigarettes may generate formaldehyde-forming chemicals at a greater level than smoking, which was determined to be a lifetime cancer risk of approximately 5 to 15 times greater than smoking. [30] However, the overall safety and long-term health effects of electronic cigarettes is still ...
