Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose lump on groin, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "lump on groin" as a symptom.  Here are eight of many possibilities (more below):
  • Enlarged Lymph Nodes
  • Sarcoidosis
  • HIV/AIDS
  • Chronic Fatigue-Fibromyalgia
  • Lymphatic Congestion
  • Valley Fever (Coccidioidomycosis)
  • Vasectomy Side-Effects
  • CLL Leukemia

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
Latin / Hispanic ethnicity
being at risk of HIV/AIDS
severe non-specific arm pain
watery eyes
strong-smelling urine
somewhat disturbed sleep
multiple swollen cervical nodes
having had a vasectomy
Asian ethnicity
weak appetite
candidiasis
constant fatigue
... and more than 90 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of lump on groin:
Cause Probability Status
Vasectomy Side-Effects 96% Confirm
Enlarged Lymph Nodes 26% Unlikely
Sarcoidosis 17% Unlikely
Valley Fever (Coccidioidomycosis) 1% Ruled out
CLL Leukemia 1% Ruled out
HIV/AIDS 0% Ruled out
Chronic Fatigue-Fibromyalgia 0% Ruled out
Lymphatic Congestion 0% Ruled out
* This is a simple example to illustrate the process
