We hear everywhere that we should eat more plant-based food. There is more plant-based food in the supermarkets, like oat milk, almond milk, vegan cheeses, and vegan yoghurts. But is all this healthier for us?

I have recently read an article about Jung’s Five Pillars of Good Life. He was a Swiss psychiatrist and psychoanalyst who founded analytical psychology. He was born in 1875 and died at age 85 in 1961. I believe that his pillars are valid even now.

Why do many people overeat chips, cereals, cakes, puddings, and other ultra-processed foods despite knowing they may not be healthy? According to science, it may be due to manufacturing processes that “predigest” raw food ingredients, creating ultra-processed foods that bypass the body’s signals of fullness.

Research has consistently demonstrated that education levels play a crucial role in reducing all-cause mortality, including cancer mortality, across all age groups and demographic profiles. A comprehensive study published in Lancet Public Health in 2024 confirmed this relationship: for every additional year of education, the risk of cancer mortality decreases by an average of 1.9%.

I have recently read a study called WISER Survivor Trial: Exploring the Effects of Exercise and Weight Loss on Inflammation in Breast Cancer Survivors. This study was done as obesity and physical inactivity are known to increase the risk of breast cancer recurrence and cardiovascular disease.

The journey through breast cancer can often feel like a relentless hamster wheel - a never-ending cycle of appointments, treatments, and a roller coaster of emotions. This journey is not a simple, straight path, but rather, it is marked by different phases, each with its own unique challenges and experiences. These phases include the initial diagnosis, the treatment period, the cessation of active treatment, and life after breast cancer.

I have recently read an interesting study from the USA that looked at breast cancer mortality rates from 1975 to 2019. This study found a substantial decline in breast cancer deaths for women aged 30 - 79 years in the USA. The age-adjusted mortality rate went down from 48 in 100,000 women in 1975 to 27 in 100,000 women in 2019.

Daniel Lieberman, a professor who has written the book "Exercised" and holds a teaching position at Harvard in the field of human evolutionary biology, has intriguing thoughts and insights about exercise, the act of sitting, and sleep. Lieberman is a firm believer in the concept that any form of movement, regardless of its intensity, even something as seemingly insignificant as fidgeting, can have beneficial impacts on our health.

I often see patients who struggle at times making decisions about which surgery to have for their breast cancer, whether to have breast-conserving surgery (lumpectomy, wide local excision, partial mastectomy) or mastectomy. I am wondering whether the 10-10-10 rule would be useful in their decision-making.

I have found this study to be one of the most interesting ones in 2023. It is a study from Yale as well as Dana-Faber/Harvard Cancer Center looking at the impact of exercise in nutrition on women undergoing adjuvant (after surgery) or neoadjuvant (before surgery) chemotherapy in women with a diagnosis of breast cancer.

New Year's resolutions are a common tradition for many people around the world. It is a time when individuals reflect on the past year and set goals for self-improvement in the coming year. These resolutions can range from adopting healthy habits or letting go of bad habits, pursuing personal growth, or achieving career milestones.

Taking annual leave is vitally important for everyone as it allows us to rest, recharge, and maintain a healthy work-life balance. However, many people fail to use all their entitled days, which can have a profound impact on us.

Endocrine modulators, also known as endocrine disruptors, are substances that can interfere with the endocrine system in humans and animals. The endocrine system is a complex network of glands and hormones that regulate various physiological processes in the body, including growth, development, metabolism, reproductive function, and immune response.

The risk of breast cancer associated with hormone replacement therapy (HRT) has been a topic of concern and discussion for both healthcare professionals and women. However, it is important to note that the perceived risk of breast cancer with HRT is often exaggerated and may influence decisions about its use.

Health and fitness industry promotes exercise for weight loss and tells that weight loss is healthy and positive. Is it correct? Such information certainly makes us feel that we are not enough and need to spend money to feel better about ourselves.

Health and fitness industry is getting bigger and bigger. Many go to fitness classes, drink healthy smoothies or use personal trainers who make us work hard to achieve perfect bodies.

Breast density is a breast imaging term that is assessed at the time of the mammogram. Increased breast density means having a higher proportion of parenchymal breast tissue (breast glands, ducts and supportive tissue) relative to fatty breast tissue.

On the mammogram, very dense breast tissue appears white while fatty non-dense tissue appears black. Increased density is associated with younger age, lower body mass index (slimmer women) and women who take hormone therapy for menopause.

Recent articles from Stuff and JAMA Surgery spoke about higher rates of infertility and pregnancy complications in female surgeons.

The JAMA study that the Stuff article was based on is not well-conducted research. It compares female surgeons to the general population. It is suggested that higher infertility rates are related to operating theatre risks. It is an incorrect way to conduct research.

Many patients of mine ask me if it's safe to use supplements during chemotherapy. My usual answer is "we do not know, so it's probably best if you do not take anything".

A recent study published in the Journal of Clinical Oncology showed that the use of supplements had been associated with worse outcomes in breast cancer patients.

It has been two weeks since New Zealand has gone into lockdown. Some people have been worried about the way healthcare is operating during this time. Especially people who have had developed cancer or those concerned they may have it.

I wanted to write this to reassure you that things are going fine. We doctors are committed to providing excellent care and minimising patients' exposure to coronavirus during their time in hospital.

Ultra-processed food is cheap, mass-produced and hyper-palatable ready-to-eat food. It includes packaged snacks, sugary drinks, bread, confectioneries, ready-made meals and processed meats.

It is known that ultra-processed food consumption is associated with an increased rate of mortality. Consumption of this food has significantly increased in the Western world, especially the USA, Australia, UK and New Zealand. The French government has developed a policy aiming to decrease ultra-processed food consumption. Possibly the New Zealand government should do the same.
