Breast cancer is the most common type of cancer among women and is the second leading cause of cancer death in women.
This type of cancer has an impact on society, because it is very frequent and because it attacks an organ full of symbolism for a woman – motherhood and femininity. Despite being rare, breast cancer also affects men, in Portugal, about 1% of breast cancers are in men.
Over the years, there has been a continuous investigation: new data are discovered about its causes and new ways of preventing, detecting and treating. All the work with the objective of improving the quality of life and the chances of cure for the various stages of the disease. Several doctors are conducting clinical trials on volunteers to try to discover and test new methods. In addition, with the same importance, psychological effects of the disease and ways to improve the comfort and quality of life of patients are being studied.
Anyone who participates in a clinical trial has a chance to benefit from new approaches and will contribute to the advancement of medicine.
🚫 According to the World Health Organization, there are an estimated 2.3 million diagnoses of breast cancer in 2020 (11.7% of the total), which is currently the most common cancer in the world.
The colorectal cancer is the second leading cause of death by cancer in the Western world, despite being one of the easiest to prevent.
About 1 in 20 people has a chance of contracting the disease, usually appearing under the age of 50. It is estimated that 3% to 4% of people, female or male, under 10 years old, will develop the disease.
It is estimated that 14% of all cancers diagnosed annually are located in the colon or rectum. Note that the colorectal cancer rate is rising, probably in some way related to the socio-economic development.
The prevalence of the disease is higher in more industrialized countries, such as the USA and Western Europe, being lower in Africa or South America.
Most cancers of the colon and rectum develops from a cell or group of cells lining the intestinal wall. These cells multiply and organize into a small non-cancerous tumor called a polyp.
As it grows, a polyp can turn into cancer. This means that it has the ability to invade neighboring tissues. This “invasion” takes place through the intestinal wall or is done at a distance, to other parts of the body, through the lymphatic and / or blood circulation.
Leukemia is a cancer of the most primitive cells in the bone marrow, the stem cells. Bone marrow is the organ where the cells of the blood, the mature cells, are formed. These cells form from stem cells, which are more primitive.
The main leukemias are:
-Acute lymphoblastic leukemia – is the most common type of leukemia in pediatric age;
-Acute myeloid leukemia – affects both adults and children;
-Chronic lymphoid leukemia – mainly affects adults;
-Chronic myeloid leukemia – mainly affects adults.
The incidence of acute lymphocytic leukemia varies with age, with the highest peak incidence occurring between 2 and 5 years of age, decreasing during adolescence and early adulthood, and rising again with aging. This type of leukemia affects 20%-30% of children with cancer, representing approximately 25% of diagnoses in children under 15 years of age. It is the most common type of acute leukemia in the pediatric population and is responsible for the majority of cancer deaths in children.
