Skin cancer

-
Screening for skin cancer in the general population is not recommended . in areas of high prevalence, education of the public in primary prevention (use of sunscreen products, hats  and other protective clothing ) and in early detection (self-referral for suspicious lesions )in more rational.
Resource levels required. Low for screening by inspection of exposed skin by primary car workers, but the technique needs validation ; high for biopsy and surgery.
Liver cancer



Screening is not recommended . no accurate screening test exists, and there is no evidence of any benefit from early detection. Emphasis should be on primary prevention through community-wide action for the prevention of hepatitis B infection, especially in infants .

  Children can get pneumonia through various means, and the most common cause is infection with bacteria, viruses, or other microorganisms. The infection typically enters the lungs, causing inflammation of the air sacs and leading to the development of pneumonia. Here are some common ways children can contract pneumonia: Bacterial Infections: Bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus can cause bacterial pneumonia. These bacteria can be spread through respiratory droplets when an infected person coughs or sneezes. Viral Infections: Viruses, including respiratory syncytial virus (RSV), influenza (flu), and adenovirus, are common causes of viral pneumonia. Viruses can be transmitted through respiratory secretions or by touching surfaces contaminated with the virus. Aspiration: Inhaling foreign objects, such as food, liquids, or vomit, can lead to aspiration pneumonia. This is more common in young children who may not have fully develo...

Is the cost of the screening and timely intervention operation warranted,given all the considerations covered in items 1-6 above, in comparison with alternative uses of the resources

Will the operation divert resources from other measures that are likely to be more effective? What other ways are there of addressing the problem that do not involve screening ? are these better? Will the screening operation divert health workers attention from more crucial efforts addressing the principal health problems of the population ? will it accomplish little but create the impression among the public that their problems are being dealt with and divert their attention from issues of higher priority ? In order to answer these questions , the costs and benefits of the proposed screening and intervention activities must be weighed against those of alternative strategies, taking into account both direct and indirect, as well as immediate and future , benefits . When planned thoughtfully and implemented in a population-based fashion, screening can provide a rational bases for resource allocation. it can be used to ensure that preventive measures are applied where they will have...

It may include community based interventions at the primary care level, e.g.,special attention from teacher and families to minimize learning difficulties or deal with emotional problems affecting development. Who . all school age children and adolescents. How and when . All sources agree on the importance of monitoring growth and development at the time of school entrance ( around the age of 5-6years ) . preschool records should be reviewed at that time.
