Oral cancer was a fatal disease even into the twentieth century. Patients required extensive surgery and often had a painful recovery or went into palliative care but the result was the same. Modern medicine has thankfully provided much to our understanding, the treatment and management of patients with oral cancer.

In recent times, patients have been able to be stratified into two general but distinct categories: the first are older with a strong history of heavy smoking and/or alcohol use; the second are younger and have a history of multiple sexual partners. The distinction is important as the treatment and management are different between the two groups with the second group having a much better prognosis.

This is the story of oral cancer.

The first medical description of pernicious anaemia is from 1821. It is written by Dr James Combe and describes a previously well 47 year old corn-merchant who presented with pallor, weakness, and neurological symptoms. It would take over a hundred years before we would know how to treat this condition, and another decade after that to understand why the treatment worked.

Vitamin B12 is an essential component of our diet and only found in animal products. Deficiency in vitamin B12 can present with fatigue, anaemia (macrocytic), and neurological symptoms. The most at risk from a dietary perspective are vegetarians, vegans, and the elderly. Patients may also have an autoimmune condition (pernicious anaemia) that interferes with gastric parietal cells and intrinsic factor; the way our body can absorb vitamin B12 from our diet.

This is the story of vitamin B12.

One of the most difficult cancers to detect early has been lung cancer. Patients often present with advanced disease that and can often be fatal.

In April 2025, a new National Lung Cancer Screening program has been rolled out in Australia to detect asymptomatic patients with a significant smoking history (30 Pack-Year). Suitable patients are eligible for a free low-dose CT (computer tomography) scan on their lungs to identify any potential lesions suspicious for cancer.

This is the story of lung cancer screening.
