Summary
The increasing incidence of malignant melanoma may be due to overdiagnosis, not an epidemic. Overdiagnosis involves identifying histologically malignant but biologically benign lesions, a common issue in cancer screening.
Area of Science:
- Dermatology
- Epidemiology
- Oncology
Background:
- Malignant melanoma incidence has risen dramatically, termed an "epidemic".
- Screening for various cancers, including melanoma, thyroid, and prostate, is common.
- Overdiagnosis is a recognized phenomenon in medical screening.
Purpose of the Study:
- To investigate the role of overdiagnosis in the rising incidence of malignant melanoma.
- To define overdiagnosis in the context of melanoma and other cancers.
Main Methods:
- Epidemiologic data analysis.
- Review of diagnostic criteria for melanoma.
- Comparison with overdiagnosis in thyroid and prostate cancer screening.
Main Results:
- The rise in melanoma incidence is attributed to overdiagnosis.
- Overdiagnosis is defined as detecting lesions that are histologically malignant but biologically benign.
- This phenomenon is also observed in screening for thyroid and prostate cancers.
Conclusions:
- The apparent "epidemic" of melanoma is likely driven by overdiagnosis.
- Overdiagnosis of melanoma warrants further investigation and may necessitate changes in screening practices.
- The issue of overdiagnosis is not unique to melanoma and affects other cancer screenings.

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
Abnormal 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...
Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
