Last time I gave you the story of how my diagnosis went down, and along the way I dropped some terms and acronyms that are technical, and I didn’t go much into detail. The medical field is filled with jargon, and I was on a learning journey as well. I went through those procedures to provide answers about what was ailing me, as is standard procedure. So now walk with me as I try to help break down what everything means and more so what it felt like as the patient. You can follow links for deeper information.
The tests and imaging started with bloodwork (lots of needles- not fun) biopsies- even more needles, sigh? Surgery- yes even more pricks! Needle fatigue is real, and so much blood drawn like Dracula is my BFF. Initially, they did a full panel when I got to the ER the first time, and it went through parameters like hemoglobin, liver, and kidney function, etc., to get a picture of how my body was doing. More about what that entails here. This was not strange as it’s common on most hospital visits. The next suggestion was CT scan and MRI. Let's have a look at those imaging techniques.

CT ( computed tomography) also known as CAT, is an imaging technique that uses X-rays to produce 3-dimensional images of internal organs, and in my case they used contrast, which is an iodine dye injected during the scan to enhance the image. The process is short, fewer than 15 min for the scanning bit and it wasn’t noisy. In cancer diagnosis, this is a primary technique of visualising tumours, and during the treatment, I will undergo more.

MRI (magnetic resonance imaging) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body They involve a much noisier and longer process. Oh, and did I add that you have to lie still to avoid blurring the image? The tube is also longer than the CT scan one, so now you get the picture of lying down completely still in a cold room with your head inside a tube making loud noises for the best part of an hour- not a pleasant experience, more so if you are claustrophobic! At least they give you ear protection for the noise. Note: due to the magnetic field, no metallic items, so unfortunately, no headphones for music… I avoided this test in my first hospital visit, but encountered it later on at the cancer centre and will do more later. Similar to CT contrast dye is also used.
Another imaging method used was ultrasound, which is a bit self-explanatory, using sound waves to view inside the body. Famously used for viewing foetuses and used on my neck .

The techniques I've mentioned above are used widely in medicine, and in the case of cancer diagnosis there is a particular type called a PET-CT scan that plays a crucial role in staging of the disease and I'll go into more detail. PET stands for Positron Emission Tomography which uses a radioactive tracer to create images used in cancer diagnosis as well as brain and heart conditions. The tracer, in addition to being radioactive is high in sugar and this helps it latch on to tumours so that their activity can be located all over the body. On the scan tumours and other areas of inflammation or high activity appear as bright spots on the image, and the radiologist uses the images for their assessment of disease spread. In order to heighten the sugar sensitivity further fasting for at least 6 hours is ordered before the scan, and in addition, I didn't eat carbohydrates for at least 24 hours. All these instructions are given when you book the test and are fairly straightforward. The tracer takes about an hour to spread through the body so I had to sit alone for 50 minutes after the injection (yes, no escape!)before going in. The scan itself was somewhere in between CT and MRI in both comfort and time. The noise was much less, and the tube is wider so less cramped and once again towards the end a tracer was injected for the CT part. All in all a relatively painless experience, and the results were immediately available in digital format on a USB drive, with the final report taking 2 working days. Due to the tracer, I was literally radioactive for a few hours after and had to stay away from young children and pregnant women! I also had to drink lots of water to flush it out.

Lastly is endoscopy, which uses a camera and a flexible tube to look inside. I also had a laryngoscopy, which used a rigid tube to look down my throat. This method is commonly used for the digestive tract, both the upper end and the lower end in the form of colonoscopy. Endoscopic techniques were also used during my initial surgery.

I hope you now have a better picture( pun intended) of cancer diagnosis and have some questions answered. As always, thanks for reading!
