A new study published in JNCI: Journal of the National Cancer Institute found that high marine ϖ-3 polyunsaturated fatty acid intake is associated with a lower risk of microsatellite instability (MSI)-high colorectal cancers. However, this relationship was not observed for MSI-stable (MSS) CRCs.
Research shows exercise slows tumor growth and improves blood vessel perfusion, leading to reduced hypoxia and better response to chemotherapy. Exercise combined with chemotherapy results in slower tumor growth compared to sedentary mice or those treated with the drug alone.
Researchers found sap-feeding butterflies have proboscis conformations closely resembling the Golden Ratio, suggesting a connection between feeding habits and substrate type. The study suggests this discovery can be used to predict the feeding habits of unstudied lepidopteran species.
Researchers found that seven severe mortality-associated diseases are less prevalent in long-lived family members than the general population. These include Alzheimer's, hip fracture, diabetes, depression, prostate cancer, heart failure, and chronic kidney disease.
A study published in JNCI found that most online cancer care websites offer nonstandard and unvalidated genetic tests, despite marketing them as personalized and effective. The vast majority of companies promoting these tests do not have evidence to support their clinical utility.
A recent study published in the American Journal of Hypertension found a strong association between adolescent BMI and both systolic and diastolic blood pressures. The study, which examined over 715,000 Israeli adolescents, revealed a significant increase in obesity rates and high blood pressure among teens.
A new UK-based study reveals that statin users have a lower risk of developing liver cancer compared to non-users. The study found the association was strongest among current users and those with pre-existing conditions like diabetes or liver disease.
A recent study published in JNCI: Journal of the National Cancer Institute found that tumor location in colorectal cancer may influence survival. Patients with left-sided primary tumors had better survival outcomes than those with right-sided tumors, suggesting potential differences in gene expression patterns and cancer biology.
A new study by Kevin Shafer and Garrett T. Pace found that having multiple parental roles is negatively associated with psychological well-being for both men and women. Childlessness is more negative for women, while specific role combinations affect mothers and fathers differently.
Epidemiological and pre-clinical studies suggest coffee has a protective effect against non-melanoma skin cancers, but the link to cutaneous melanoma is less clear. A study found that high coffee intake was inversely associated with a 20% lower risk of malignant melanoma, especially in caffeinated coffee drinkers.
A recent study published in JNCI Journal of the National Cancer Institute found no association between migraine and breast cancer. The researchers analyzed data from 115,378 women and concluded that migraine was not associated with breast cancer risk or differences in endogenous sex hormone levels.
Breast cancer patients taking brand name aromatase inhibitors had higher discontinuation rates and nonadherence compared to those on generic AIs. Higher copayments of $15-$30 per month were also linked to discontinued use.
A new study by Jonathan Marc Bearak reveals that the odds of unprotected intercourse in college hookups increase dramatically between freshman and senior year. The research suggests that lower socioeconomic students initially prioritize condom use but eventually adopt similar rates as their more advantaged peers.
A recent study found that a higher overall diet quality was associated with a lower risk of mortality among ovarian cancer survivors. The composite effect of healthy dietary choices on survival suggests that individual components may not be as crucial as previously thought.
A new study finds that primary-grade retention has lasting effects on educational attainments, reducing high school completion odds by about 60%, and operates mainly at high school completion. Grade retention leaves lasting scars on students' educational careers.
A new study published in the American Journal of Hypertension suggests that sodium intake has a minimal impact on blood pressure. Higher consumption of fruits and vegetables was shown to significantly lower blood pressure, while increased physical activity showed no noticeable effect.
A recent study published in JNCI Journal of the National Cancer Institute found that soy supplementation altered the expression of genes associated with breast cancer. The study involved 140 patients who were randomized to either soy supplementation or placebo, and observed changes in several genes that promote cell cycle progression a...
A recent study found that HPV testing alone provides similar reassurance against cervical cancer as cotesting and even more so than a negative Pap test. This suggests that primary HPV testing every 3 years could be an effective screening strategy.
A new study published in JNCI: Journal of the National Cancer Institute found that breast cancer screening costs increased substantially among older women between 2001 and 2009, despite unchanged detection rates of early-stage tumors. The study analyzed data from the SEER-Medicare linked database and found a significant increase in scr...
A recent study published in JNCI: Journal of the National Cancer Institute found that contralateral prophylactic mastectomy (CPM) may confer only a marginal life expectancy benefit depending on the type and stage of cancer. The procedure was more beneficial for younger women and those with stage I and ER-negative breast cancer.
A study published in JNCI: Journal of the National Cancer Institute found that a shorter time to first cigarette (TTFC) is associated with an increased risk of lung cancer in both heavy and light smokers. The researchers analyzed data from over 3,200 current and former smokers, revealing that TTFC was statistically significantly higher...
A meta-analysis of 43 studies found that sedentary behavior increases the risk of colon, endometrial, and lung cancers. The risk increases with sitting time, even among physically active individuals, suggesting a detrimental impact on cancer prevention.
A study found that smokers are more likely to quit after receiving a serious lung cancer screening result. The effect appeared to be durable, lasting up to 5 years after the last screening.
A study published in JNCI: Journal of the National Cancer Institute found that indoor tanning increases melanoma risk, regardless of burn history. Researchers matched 1167 melanoma patients with 1101 control subjects and found nearly four times more indoor tanners among those with zero burns.
Researchers found that patients with tumor cells in their blood after surgery had a higher risk of relapse and poorer survival rates. The presence and count of tumor cells also predicted disease-free survival, with those having 5 or more CTCs at higher risk of recurrent disease.
High total and saturated fat intake associated with greater risk of ER+PR+ breast cancer and HER2- disease. A high-fat diet increases BC risk, especially receptor-positive disease linked to saturated fat intake.
A study published in the American Journal of Hypertension found that most Americans' daily sodium intake is associated with better health outcomes than current CDC recommendations, which are now viewed as excessively low. The ideal range is between 2,645-4,945 mg/day, where health outcomes remain favorable.
A new study found that adjuvant chemotherapy increases markers of molecular aging in the blood of BC survivors, including p16INK4a and ARF expression. These age-promoting effects may last for several years after treatment and even be permanent.
