Each year, about 1,800 children suffer from cancers in France, or 1 child in 600. The treatment and support of these young patients have improved but are still insufficient, according to the associations of families of patients. On the occasion of the world cancer day of the child, which will be held February 15, Doctissimo takes stock of the current situation.
Cancers of young people under 15 years old are rare and represent only 1% of all cancers. They are often ignored and their support is harder that support developed for adults is not necessarily suitable for the youngest.
Childhood cancer is rare
Each year, about 1,800 children and adolescents suffer from cancer, although the cure rate has increased these past 30 years, from 25% to 80%. This is the 2nd cause of mortality in the child over the age of 1 year (after accidents), causing 500 deaths per year. Continue reading “Childhood cancer: support to improve”
Facing pediatric cancers, early detection and appropriate treatment are the main measures. Medical advances now allow to cure three children in four developed countries.
Organized by the International Union against cancer (UICC), world day of cancer called 2006 ‘My child, my battle’ insists on the importance of equal access to care (14 projects will be launched by the UICC in 2006 in ten poor countries) and screened early1.
Few identified risk factors
Because the causes of childhood cancers remain largely mysterious. They most likely result from a lack of development of organs, already present sometimes in an embryonic State. Because of these genetic origins, no preventive measure concerns currently pediatric cancers. Some environmental risk factors have been advanced. The only well-established is exposure to ionizing radiation on children but also on the pregnant woman. Other factors remain more controversial as proximity to high-voltage lines and fields electromagnetic2, exposure to chemicals of parents3, certain infections4, smoking parents5… Continue reading “Childhood cancer”
For treating pediatric cancers, girls receive a chest radiotherapy. Essential element of support, this technique exposed however to an increased risk of developing breast cancer later. This driving would be comparable to that of women with genetic predispositions to disease. The results of this study presented to the US Congress of cancer advocates early screening.
Women who received radiation therapy to treat cancer in childhood should be screened for early breast cancer. Radiation therapy remains an essential element of support of many pediatric cancers. But this technique can increase the risk of developing breast cancer chest exposure. But in what proportion? Out the1 study presented at the American Congress on cancer ASCO 2012 sought to compare this risk to that related to genetic predispositions. We analyzed the data over 1 200 women who had chest radiation therapy to treat pediatric cancer. The risk associated with genetic predispositions (genes BRCA1/BRCA2 alterations) was evaluated on the study WECARE including 4 570 women with a relative of first degree of breast cancer and who was in life a year after diagnosis.
For those having a pediatric cancer, close to a woman aged 50 years on 4 (24%) had breast cancer. Among those treated for Hodgkin’s lymphoma, the disease was almost one woman in three (30%), a risk the same as women with genetic predisposition BRCA1 (31%) – the risk associated with BRCA2 is estimated at 10%. In comparison, the risk to the general population of women 50 years of age is 4%. Continue reading “The Health News”
