What Is Cancer?
In order to help yourself, or those around you affected by cancer, you first need to understand what cancer is. This in itself is one of the biggest challenges as cancer is such a complex and multifaceted disease.
In short, cancer is the result of DNA mutation, which results in a genetic disease. Mistakes and issues in our DNA, of which we cannot control, can result in uncontrolled cell growth.
Normal cells regulate life, death and everything in between
When cancer is present, normal cell control no longer works, which means dangerous cancerous cells can grow unchecked and ultimately spread to other parts of the body.
It is part of our human nature to try and protect ourselves, it is only natural for us to avoid pain and seek pleasure. Sadly, cancerous cell division is out of our control.
Similar to humans, cancer also follows the survival process. The growing disease seeks immortality by avoiding the body's checks and balances the irony is that cancer's success is really a failure as unchecked growth ultimately leads to its own death.
How does a normal cell become a cancerous cell?
There are trillions of cells within the body, but it only takes one to go wrong to mess everything up.
This process doesn’t happen overnight, cancerous cells develop slowly over a long period of time. The process of diverging from their normal state to the cancerous state can take between 2 and 40 years, causing numerous problems along the way. At each stage of the process the cancerous cells follow a similar process, some quicker than others.
Firstly, certain changes occur in the DNA before the cell even becomes cancerous, then additional DNA damage occurs that knocks out the body's defenses against this growth cells no longer obey signals to stop growing or commit suicide.
Further DNA damage then allows cells to access the body's blood supply, meaning the growing cancer mass can nourish itself with nutrients and survive. Further genetic defects allow the cells to move from the original cancer site to other parts of the body this process of movement is known as cancer metastases.
Over 90% of cancer deaths result from metastases, and it is this ability to move around the body that distinguishes malignant from benign tumors.
Ultimately, it is thought that all cancer starts from a single cell that has, over time, experienced a combination of DNA changes that allow it to grow unchecked and avoid the body's inbuilt safety mechanisms.
Diet, exercise, lifestyle and cancer
There are many studies and research papers that highlight the link between exercise, endorphin release, and positive mood. The process is no different when it comes to helping yourself with cancer.
Eating well can help your body at all stages of the cancer journey from diagnosis, through treatment and recovery. Following a balanced diet can also influence those around you to lead a healthier lifestyle, meaning the impact can go beyond those living with cancer.
Much research considers food to be a key element in your armory against cancer following diagnosis, whatever your stage. This is not to replace treatment, but to support alongside medical advice to get the most out of your treatment and to boost your resilience.
There's no single study proving it will help, and there's no single food that's a miracle, but there is enough evidence to suggest that some food choices can be of real benefit. This is not just in how patients feel, but also maximizing your health while living with disease, preventing recurrence, or living well in a palliative situation.
Help yourself and those around you
After a cancer diagnosis, overall diet quality and choosing particular foods can be very helpful for supporting health and resilience. These choices can also contribute to other aspects of your health and well being.
After a cancer diagnosis, dietary needs can change, especially at different stages of cancer and particularly at different stages of treatment. Studies have identified foods that can help prevent cancer, and foods that may increase cancer risks.
For people living with and beyond cancer, a better quality diet is associated with longer survival according to studies. Some foods with particular anti-cancer properties have been identified.
Overall, a higher intake of plant foods is beneficial, providing an array of vitamins and minerals, and particularly phytonutrients, botanical compounds in certain foods are especially valuable as they have anti-cancer properties.
Reducing or avoiding red and processed meat is advisable as there are compounds in these foods that may trigger cancers to start. Very recent research suggests that eating plenty of fibre helps to support a healthy population of microbes in the digestive system, and this can have a benefit for immunity. Healthy unprocessed fats such as olive oil, and oily fish provide essential fats that help healing and may help reduce inflammation. Individual needs may differ, and dietary changes need to be considered for each person's situation and taking account of other restrictions they may need to follow.
