Preventive Healthcare Services

1.1K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Skin Cancer01:30

Skin Cancer

4.3K
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Cancer Prevention02:59

Cancer Prevention

6.2K
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.

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

5.4K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Changes in Skin Color: Clinical Perspectives

2.0K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Cancer Vaccines01:30

Cancer Vaccines

456
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Summary
This summary is machine-generated.

The US Preventive Services Task Force found insufficient evidence to recommend skin cancer screening for asymptomatic individuals. More research is needed to determine the benefits and harms of visual skin examinations.

Area of Science:

  • Dermatology
  • Preventive Medicine
  • Oncology

Background:

  • Skin cancer is the most common cancer in the US, with melanoma causing the most deaths.
  • Melanoma is more prevalent in White individuals but often diagnosed later in those with darker skin.
  • Early detection and treatment are crucial for better outcomes.

Purpose of the Study:

  • To update the 2016 recommendation on skin cancer screening.
  • To systematically review the benefits and harms of screening asymptomatic individuals.
  • To inform clinical practice guidelines for skin cancer detection.

Main Methods:

  • Systematic review commissioned by the US Preventive Services Task Force (USPSTF).
  • Focused on screening for skin cancer in asymptomatic adolescents and adults without a history of skin lesions.
  • Evaluated evidence on the benefits and harms of visual skin examination by clinicians.

Main Results:

  • The USPSTF found insufficient evidence regarding the benefits and harms of screening.
  • The current evidence does not support or refute the routine screening of asymptomatic individuals.
  • Further research is required to establish the efficacy of skin cancer screening.

Conclusions:

  • The USPSTF concludes that evidence is insufficient to assess the balance of benefits and harms of visual skin examination for skin cancer screening.
  • An "I" statement indicates insufficient evidence.
  • The recommendation for skin cancer screening in asymptomatic populations remains undetermined.
