Pancreatic cancer is one of the most challenging cancers to detect early, often progressing without clear symptoms. Key early warning signs include sudden swelling in one or both legs, which may indicate Deep Vein Thrombosis (DVT) due to obstructed blood flow. Other symptoms to watch for include persistent pain in the leg muscles, discoloration of the skin, and warmth in the affected area. Additionally, patients may experience jaundice, loss of appetite, unexplained weight loss, abdominal pain, and fatigue. These signs should not be overlooked, and it is essential to consult a healthcare provider for proper evaluation if they occur together or persist.
