Advertisement for a healthy diet to possibly reduce cancer risk. An average 35% of human cancer mortality is attributed to the diet of the individual. [9] Studies have linked excessive consumption of red or processed meat to an increased risk of breast cancer, colon cancer, and pancreatic cancer, a phenomenon which could be due to the presence of carcinogens in meats cooked at high temperatures.
Extracts from Camptotheca (the "happy tree" or "cancer tree") were used to develop the chemotherapeutic drug Topotecan. Plant sources of anti-cancer agents are plants, the derivatives of which have been shown to be usable for the treatment or prevention of cancer in humans. [1] [2]
Cancer slope factors (CSF) are used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit , on the increased cancer risk from a lifetime exposure to an agent by ingestion or inhalation .
For breast cancer, there is a replicated trend for women with a more "prudent or healthy" diet, i.e. higher in fruits and vegetables, to have a lower risk of cancer. [18] Unhealthy dietary patterns are associated with a higher body mass index suggesting a potential mediating effect of obesity on cancer risk. [19]
Research has shown, when drug use begins at an early age, there is a greater possibility for addiction to occur. [14] Three exacerbating factors that can influence substance use to become substance use are social approval, lack of perceived risks, and availability of drugs in the community. Youths from certain demographics are also at higher ...
The main exposure to UFPs is through inhalation. Owing to their size, UFPs are considered to be respirable particles. Contrary to the behaviour of inhaled PM 10 and PM 2.5, ultrafine particles are deposited in the lungs, [13] where they have the ability to penetrate tissue and undergo interstitialization, or to be absorbed directly into the bloodstream—and therefore are not easily removed ...
Responsible drug use seeks to maximize the benefits and minimize the risks associated with psychoactive drug use. For illegal psychoactive drugs that are not diverted prescription controlled substances, some critics [1] [2] believe that illegal recreational drug use is inherently irresponsible, due to the unpredictable and unmonitored strength and purity of the drugs and the risks of addiction ...
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
