Summary
Cancer incidence varies across the human lifespan, often increasing with age due to accumulated events. Understanding cancer
Area of Science:
- Oncology and Gerontology
- Cancer Biology and Epidemiology
- Human Lifespan Development
Background:
- Cancers are diverse diseases with unique evolutionary paths and host responses.
- Cancer incidence shows regional variations and an increasing trend at younger ages.
- While many cancers manifest later in life, their origins trace back to earlier stages.
Purpose of the Study:
- To analyze the temporal patterns of cancer incidence across the human lifespan.
- To investigate the relationship between aging, accumulated events, and cancer manifestation.
- To explore potential reasons for the decline in cancer incidence late in life.
Main Methods:
- Review and analysis of epidemiological data on cancer incidence across different age groups.
- Correlation of cancer manifestation timing with cumulative life events and aging processes.
- Exploration of cohort effects and late-life biological factors influencing cancer risk.
Main Results:
- Cancer incidence is spread across the lifespan, with a notable increase in later years, but originating earlier.
- Late manifestation appears linked to accumulated events over time, not solely aging.
- A decline in cancer incidence is observed late in life, suggesting resistance or unique late-life factors.
Conclusions:
- Neoplastic disease evolution is a continuous process influenced by early aggressions, susceptibility, and developmental changes.
- Understanding lifespan cancer incidence is crucial for deciphering both cancer and aging.
- Further research is needed to clarify late-life cancer incidence patterns and their underlying mechanisms.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
02:12What is Cancer?
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
