Tumors - suggest that some repressed memory or feeling remains unsettled and is threatening to emerge into your consciousness.. or a part of yourself, or a belief, has gone awry.

Coral/lung(irregular) shape - Shapes are visual symbols of the internal, psychological structure. Because the mind, and our emotions, appear so abstract, it's hard to have a clear image of our differences when compared with other people. Shapes, symbols, patterns, and textures gives us an 'image' of our inner world.
Because of the irregular shape, it suggests you feel your life is a bit chaotic, or unstructured, at the moment.

Bleeding - Blood is a symbol of vitality. Bleeding suggests a "weakening" of your energies and frustration at this moment in your life. Dreaming about bleeding usually points to the emotional wounds that you don't acknowledge, or are just becoming aware of.

Leg - Legs symbolize support, motivation, the emotional, and physical, strength you use to get about in life. We may depend on others for support at home, work, or school for self-value. But, ultimately, our legs represent our emotional, or conceptual(idealistic), and personal support system. (Example: ..."Standing on my own two feet"..."I don't have a leg to stand on"...)

Left leg - The left side represents inner feelings that support outer actions, such as confidence, self-assurance, faith, beliefs, and our 'lesser-used', supportive functions.

Expessing the need to go to Hospital - a symbol of care and recovery. You may be feeling the need for physical, psychological, emotional, or spiritual healing.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Have you lost faith, or confidence, in yourself, or something/someone you believed in?
Do you feel a sort of loss because of something you learned about someone, or something?
Do you feel 'let down' by someone you thought was a friend?
Did someone turn out to be the opposite of what you expected?
Did some situation prove to be a negative experience, or worse than you thought it would be?

I hope this gives you some insight to your dream.
Best wishes!

Now that you've had a chance to step back for a while, I'm sure you will do what's best for you.

Best of luck!!
