Diet Therapy for Cancer
The relationship between food and cancer has two different aspects. On the one hand, considering the diet as factor promoting cancer, on the other, the role diet has in the treatment of cancer patients.
Until recent years, it was not easy to establish a clear and direct relationship between food and cancer. Different studies did not individually demonstrate clearly, neither the degree of relationship, nor the moment of cancer development in which some foods or certain eating habits are involved. However, there are so many studies carried out and so wide the information collected in them, that when studying the problem from a global and inclusive perspective the results are more than convincing.
Diets rich in meats and fats and some vitamins and micronutrients have obtained, after many studies, qualifications of cancer promoters or cancer protectors, respectively.
Adjusting the diet for the treatment of cancer patients has given very positive results in recent years, allowing a better quality of life for patients undergoing curative or palliative therapies.
In recent years, scientific studies on the metabolism of cancer cells have shown many differences in how a cancer cell feeds according with the type of cancer. Some tumors, such as prostate, feed primarily on fats, others primarily on glucose and others, such as pancreatic cancer, combine a high intake of glucose and proteins. Knowing the metabolic pathways most used for each cancer type, we can design personalized diets helping to reduce cancer growth.

Resveratrol and cancer
Numerous studies on resveratrol have shown great potential in the treatment of different types of cancer, due to its ability to affect several molecular pathways. Resveratrol has proven the ability to eliminate tumor stem cells, which are the main inducers of tumor growth.
Ketogenic diet and cancer. Allowed foods
The ketogenic diet consists of drastically decreasing carbohydrates in the diet, as these are the source of glucose. Instead they are replaced with large amounts of healthy fats. With not enough glucose available to use as an energy source in the body, the body begins to form ketone bodies from fats. Ketone bodies can be used by healthy cells for energy, but not by tumor cells.
Cúrcumin and Breast Cancer
Curcumin has shown antitumor effects in breast cancer. HER2 positive. It can induce cell death in breast cancer cells by inducing changes in the cell membrane potential. Cancer stem cells are one of the main causes of cancer recurrence after treatment. Curcumin has shown its ability to kill cancer stem cells, in addition to increasing the effectiveness of chemotherapy.
Quercetin and Cancer
Quercetin is a type of flavonoid compound that comes from nature and is widely found in our diet. Quercetin can exert antitumor effects by altering cell cycle progression, inhibiting cell proliferation, stimulating apoptosis or cell death, inhibiting the progression of angiogenesis or formation of new blood vessels that feed the tumor and metastases.
Lycopene and Cancer
The anticancer effects of lycopene involve modulation of pathways that slow tumor growth and inhibit tumor progression. This article aims to evaluate the benefits of lycopene supplementation in the prevention and treatment of cancer based on the results of scientific studies.
Tumor Markers for Cancer
In cancer treatment, accurate follow-up is critical to improve treatment outcomes and patient survival. In this sense, tumor markers are a valuable tool in cancer diagnosis and monitoring. They allow us to quantify tumor activity and response to treatment long before performing control imaging tests (CT, PET, CT, MRI).
