Yes, studies have found a significant association between low vitamin D levels at the time of diagnosis and inferior outcomes in several types of lymphoma, including lower overall survival (OS) and progression-free survival (PFS).
Dietary Vitamin D Increases Percentages and Function of Regulatory T Cells in the Skin-Draining Lymph Nodes and Suppresses Dermal Inflammation.
Foods to Avoid
Conclusions. Several epidemiological, pre-clinical and clinical studies support vitamin D as a preventive and therapeutic cancer agent, for a wide spectrum of cancer.
Abstract. Vitamin D deficiency has been found to be associated with a variety of cancers, including prostate, multiple myeloma, colorectal and breast cancer. Several studies have shown vitamin D levels to have an inverse relation with cancer mortality, while others have considered it a potential risk factor.
Rickets is a rare disease that causes the bones to become soft and bend. African American infants and children are at higher risk of getting rickets. In adults, severe vitamin D deficiency leads to osteomalacia. Osteomalacia causes weak bones, bone pain, and muscle weakness.
Vitamin D & cancers
Low levels of 25(OH)D have been associated with colon cancer and high levels have been associated with pancreatic cancer.
Herbs and vitamins to avoid during chemotherapy
In experimental studies of cancer cells and of tumors in rodents, vitamin D has been found to have several biological activities that might slow or prevent the development of cancer, including promoting cellular differentiation, decreasing cancer cell growth, stimulating cell death (apoptosis), reducing tumor blood ...
Although vitamin D deficiency is particularly common in the elderly, in whom limited sun exposure, reduced dietary intake, and renal impairment are common, it is important to recognize that vitamin D supplementation is both inexpensive and easy to achieve as for most patients, with daily intake of approximately 800– ...
Treatments for lymphomas may include a "watch and wait" approach, chemotherapy, immunotherapy, radiation therapy, targeted therapy, and clinical trials. Treatments also may include CAR-T cell therapy, bone marrow transplant, also called bone marrow stem cell transplant, and treatments for cutaneous lymphomas.
Natural killer/T-cell lymphoma (NKTL) is a sub-type of Epstein–Barr virus (EBV)-related non-Hodgkin lymphomas common in Asia and Latin America but rare elsewhere. Its pathogenesis is complex and incompletely understood. Lymphoma cells are transformed from NK- or T-cells, sometimes both.
Lymphoma's exact cause is often unknown, but it develops from genetic damage to lymphocytes (white blood cells), leading to uncontrolled growth, with risk factors including a weakened immune system (from diseases or medications), certain viral/bacterial infections (like Epstein-Barr, HIV, H. pylori), family history, exposure to specific chemicals (benzene, pesticides), radiation, and lifestyle factors like smoking, notes Cancer Council.
Moreover, a study from the Wilmot Cancer Institute found that people with follicular lymphoma who had low vitamin D levels before starting treatment were more likely to relapse sooner or die of the disease. Vitamin D supplementation may even be helpful during lymphoma treatments.
It has been confirmed that vitamin D has potent anti-inflammatory properties. It contributes to reduction in pro-inflammatory mediators and an increase in anti-inflammatory cytokines. There is also evidence that vitamin D could decrease C-reactive protein (CRP) and affect selected haematological indices.
Symptoms of Vitamin D Excess
Early symptoms of vitamin D toxicity are loss of appetite, nausea, and vomiting, followed by weakness, nervousness, and high blood pressure. Because the calcium level is high, calcium may be deposited throughout the body, particularly in the kidneys, blood vessels, lungs, and heart.
It has been found that low serum vitamin D3 levels are associated with increased cancers of the breast (4), colon (5) and prostate (6) and animals lacking VDR or with severe vitamin D deficiency are prone to increased tumorigenesis (7,8).
Possible symptoms include:
Vit-D also reduces the expression of toll-like receptor (TLR)-2 and TLR4 on monocytes/macrophages and subsequently, down-regulates the expression of pro-inflammatory cytokines and abrogates unwanted immune responses following infectious disease and/or inflammation (Sadeghi et al., 2006).
Recent epigenomic, transcriptomic, and proteomic studies have revealed novel vitamin D-mediated biological mechanisms that regulate cancer cell self-renewal, differentiation, proliferation, transformation, and death.
The 62-day rule for cancer, primarily in the UK's NHS system, is a key waiting time target: patients who receive an urgent referral for suspected cancer should begin their first cancer treatment within 62 days from the date the hospital gets that referral. It's part of broader standards that also include a 28-day "Faster Diagnosis" goal (diagnosis or ruling out cancer within 28 days of urgent referral) and a 31-day "Decision to Treat" standard (treatment within 31 days of the agreed-upon plan).
Vitamin D is one of the most studied supplements for cancer prevention and treatment right now. Vitamin A, vitamin C, vitamin E, and beta-carotene contain antioxidants once thought to help prevent cancer.
Yes, getting too much vitamin D can be harmful. Very high levels of vitamin D in your blood (greater than 375 nmol/L or 150 ng/mL) can cause nausea, vomiting, muscle weakness, confusion, pain, loss of appetite, dehydration, excessive urination and thirst, and kidney stones.
Yes, you can do a vitamin D test at home using simple finger-prick kits (like TouchBio, 2San, We Test Bio) that provide quick, preliminary results (often in 10 mins) by analyzing a drop of blood to check if levels are sufficient, insufficient, or deficient, helping you monitor bone health and immune support, but you should always discuss abnormal results with a doctor for proper diagnosis and treatment.
Should you take vitamin D if you have cancer or while receiving chemotherapy? You should only take a vitamin D supplement if your healthcare team recommends it. Your oncologist may also recommend a vitamin D supplement to help prevent bone loss caused by certain cancer treatments.
