Cancer: Definition, Facts, and Hallmarks

Cancer is a large, diverse group of diseases. It is defined by uncontrolled cell growth anywhere in the body, with the potential to spread ("metastasize") to other organs. In 2020, an estimated 19.3 million new cancer cases and almost 10.0 million cancer deaths occurred worldwide. The most commonly diagnosed cancer is breast cancer, followed by lung, colorectal, prostate, and stomach cancers. In many countries, cancer ranks among the most common causes of death, and the numbers are increasing anually (Sung et al., 2021). This illustrates the emerging need to develop novel therapies, which can only be realized by increasing the knowledge about the highly complex fundamentals of neoplastic diseases.

Tumors can develop almost everywhere in the human body and have many different manifestations. In spite of this diversity, some characteristics apply to all types of cancer, such as the uncontrolled proliferation of cells and their potential to metastasize to other parts of the body. Whereas cancer is relatively rare in children (with leukemia as predominant childhood cancer), increasing age is a clear risk factor for being affected. Further general risk factors are genetic predisposition and various environmental effects (e.g., smoking as one of the leading causes of lung cancer and ultraviolet light for skin cancer).

Some tumor types are very aggressive: pancreatic cancer (i.e., pancreatic ductal adenocarcinoma, PDAC), has a high metastasizing rate and only a few therapeutic options, resulting in 5-year-survival rates below 8% (Orth et al., 2019). Other types have a very positive overall outcome: basalioma (basal cell carcinoma, BCC), which is the most common type of skin cancer, only rarely metastasizes and, in most cases, can be completely excised by surgery (Rogers et al., 2015).

During the process of tumor development, cancer cells acquire defined biologic capabilities. They resist cell death, induce angiogenesis, sustain proliferative signaling, evade growth suppressors, activate invasion and metastasis, and enable replicative immortality—all these processes were published as the "Hallmarks of Cancer" back in 2000 by Hanahan and Weinberg. A decade later, these hallmarks were complemented by further hallmarks (avoiding immune destruction and deregulating cellular energetics), as well as the "enabling characteristics" (tumor-promoting inflammation as well as genome instability and mutation).

With their enormous work in basic and applied cancer research, thousands of scientists contribute every day to deciphering cancer mechanisms. ibidi helps these researchers develop therapeutics against this dismal disease with a variety of tailored solutions for cell-based assays and high-end microscopy.

For a better life without cancer!
