Lung nodule Archives

Tag: Lung nodule

A solitary pulmonary nodule or “spot on the lung” is defined as a discrete, well-defined, rounded opacity less than or equal to 3 cm (1.5 inches) in diameter that is completely surrounded by lung tissue, does not touch the root of the lung or mediastinum, and is not associated with enlarged lymph nodes, collapsed lung, or pleural effusion.

A pulmonary nodule can be benign or cancerous. Lesions larger than 3 cm are considered masses and are treated as cancerous until proven otherwise.

Lung nodules are quite common and are found on one in 500 chest X-rays and one in 100 CT scans of the chest. Lung nodules are being recognized more frequently with the wider application of CT screening for lung cancer. Roughly half of people who smoke over the age of 50 will have nodules on a CT scan of their chest.

Neuroendocrine Cancer: Nodes, Nodules, Lesions (and false alarms!)

A fairly common disposition of Neuroendocrine Neoplasms is a primary with associated local/regional secondary's (e.g. lymph nodes), and often with liver metastases. Technically speaking, the liver is distant. However, many metastatic patients appear to have additional and odd appearances in even more distant places, including (but not limited to) the extremities and the head & neck. Certain things are known about the behaviour of Neuroendocrine Neoplasms (NENs) (a term for Neuroendocrine Tumours and Neuroendocrine Carcinoma) and specialists will be analysing many factors when working out the type of NEN and how it might behave. This is useful in cases of…

Incidental findings and Incidentalomas – NET or NOT

Patient AdvocacyBenign, Benign tumour, Differential diagnosis, Incidentaloma, Liver cyst, Liver lesion, Lung nodule, Physiological uptake, Renal cyst, Thyroid nodule

During my diagnostics, I presented to my general practitioner as someone with symptoms of iron deficiency anaemia with some weight loss (not a lot but some). The GP at this point had no alternative but to refer me to secondary care where they had the tools to investigate further - e.g. imaging and endoscopies. The use of laboratory testing and imaging devices are there to not only back up the a doctor's clinical hypotheses but also to test them, i.e. these laboratory tests and imaging checks may lead to others. Differential checks are not misdiagnoses, they are part of the…

Benign liver lesions and cysts – something or nothing?

Living with Neuroendocrine Cancer, Patient AdvocacyBenign, Hemangioma, Liver cyst, Liver lesion, Liver metastases, Lung nodule

Background I wanted to focus on two terms "lesion" and "cyst" given these are mentioned all the time in my online patient group, on many occasions by a worried newly diagnosed patient who has just been told (or read before an appointment) this was something found during diagnostic scans. Sometimes cysts are included in the term "liver lesions". Lesion is defined as "An area of abnormal tissue. A lesion may be benign (non-cancerous) or malignant (cancerous)". The majority of liver lesions are non-cancerous (benign) and will not be related to Neuroendocrine Cancer, or any cancer. Many lesions are detected during…

Lung nodules – something or nothing?

Living with Neuroendocrine Cancer, Patient AdvocacyLung nodule

BackgroundA focus on the issue of Lung nodules given I see these mentioned all the time in my online patient group, on many occasions by a worried newly diagnosed patient who has just been told this was found during diagnostic scans. Sometimes a lung nodule is also called a ‘pulmonary’ nodule and the two phrases mean the same thing.A lung nodule is an abnormal growth that forms in a lung. You may have one nodule on the lung or several nodules. Nodules may develop in one lung or both. Most lung nodules are benign (not cancerous). Only rarely, lung nodules…

It’s been 10 years since I saw a scalpel (….but my surgeon is still on speed dial)

Living with Neuroendocrine Cancer, Survivorship, TreatmentAdvanced neuroendocrine cancer, Axillary nodes, Carcinoid tumour, Distant metastatis, Endocrine, Ki-67, Lung nodule, Lymphadenectomy, Lymphatic system, Metastatic Neuroendocrine Cancer, Neuroendocrine, Neuroendocrine cancer, Neuroendocrine tumour (NET), Nodule, Octreoscan (Octreotide scan), Quality of LIfe (QoL), Supraclavicularfossa (SCF) lymph nodes, Surgery, Thyroid cancer

In 2012, I had a bunch of lymph nodes removed. Two separate areas were resected, only one was showing growth but both were showing up as hotspots on an Octreoscan. I had known since shortly after diagnosis in 2010 that 'hotspots' were showing in my left 'axillary' lymph nodes (armpit) and my left 'supraclavicular fossa' (SCF) lymph nodes (clavicle area). Some 10 months previously, I had a major liver resection, and 5 months prior to the liver resection, I had a small intestinal primary removed including work on some associated complications. There had always been a plan to optimise cytoreduction of my…
